Kernel 2.6.22 prevents LiveCD load

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux-source-2.6.22

Thank you for the email.
Perhaps the FindRightsPackage will provide the knowledge
which is taken for granted by enthusiasts.
I am a newbie to Linux but an experienced IT user struggling
to report a weakness in the otherwise magnificent Ubuntu 7.10

It's not a media quality problem. A Canonical copy failed to load and a slowly burnt and verified alternate CD gave a subtly different Linux failure to load into RAM. Note that all the CDs load without any problem for Windows XP inspection.

A LiveDVD appeared to load and Install but then gave problems, so I then tried burning a LiveCD as a DVD and THAT seemed to load and install via the Optiarc DVDRW AD-5170A drive. I then tried changing the MSI-supplied PATA133 interface cable for a shorter PATA166 cable and that seemed to allow the Canonical LiveCD to very slowly load.

I will next try using the CD on DVD plus the shorter interface cable to load and install Ubuntu 7.10 from the Canonical LIveCD, hoping that that will allow me to get on, but I believe that there is an intrinsic weakness in the kernel, plus a weakness in the BIOS reading of CDs in a DVD drive, so I have asked MSI if there is a better BIOS.

Meanwhile, my simple question stands. Might it be a good idea to re-release 7.10 with a 2.6.23 kernel, which appears to be stronger ?

Hi Bruce,

Thank you for your report. To answer your question, the Gutsy Gibbon 7.10 release will remain at the 2.6.22 kernel version. However, the upcoming Hardy Heron release will target the 2.6.24 kernel. The Hardy linux-source package should be appearing soon. If you'd be willing, we'd really appreciate it if you would be willing to test against the upcoming Hardy Heron release once it comes out and let us know if this issue still persists. For now I'm tagging as "hardy-kernel-candidate". Thanks!

It's been a long day, so I hope that this reply makes sense.

My work-around of improving hardware performance by
upgrading to a short PATA166 cable, plus using a LiveCD
iso image burnt to a DVD actually worked. If MSI offer
a better BIOS, reading of other CDs might be possible.
Meanwhile I have told others of my work-around, but
not my MoBo supplier who 'doesn't support Linux'

Happy to re-test later for you, I'll even hang on to a copy
of the weak BIOS if it's replaced by a better version.

(I see that Fedora-based Vixta is already using a later
kernel than Gutsy, whose 'Tribe' releases were a fair
indicator of pre-release progress.)

With more folk using SATA DVDRW drives to read the Ubuntu 7.10 LiveCD, the weakness in the way that the kernel is used to read into RAM is resulting in more and more folk failing to simply run a LiveCD session, let alone achieve installation, which is a great pity.

Similar failures are occurring with LinuxMint 4.0 (Daryna) LiveCDs.

New, but not yet available machine BIOSs may help, but I am telling people to try burning the LiveCD to DVD and try that.
It's a poor work-around, but often works !

Hi Bruce,

I just wanted to give you an update. The Hardy Heron kernel was recently uploaded for testing. Unfortunately, the Hardy Heron Alpha1 LiveCD was released with the older 2.6.22 kernel so it doesn't really help you. You'll have to manually install the newer Hardy Heron kernel in order to test the kernel. This should not be the case for Alpha2 LiveCD. Let me know if you want to manually install the kernel and I'll send you instructions on how to install but it seems like you're wanting to test from the LiveCD. Thanks.

Hi Leanne

Busy with work-arounds, I had missed the Alpha-1 release but
have now downloaded it and it's a little happier loading on my
problem PC, with its shorter, faster PATA133 cable, and
burning to DVD disc helps, but other LiveCDs are still refusing
to load into RAM.
Assembling a set of test discs, I am re-configuring several PCs
to act as test PCs for future Hardy Heron Alpha releases.

Some bad news for my Alpha release testing.

Last week, my problem MSI-G33M board finally failed.
I will therefore only be able to test on other PCs, but I will see if one of them exhibits similar problems to the failed board.

On a 3.0GHz Northwood PC, Alpha-2 release iso download passes overall MD5 checksum but fails to complete in-built CD integrity check.

Well, in-built CD integrity fail to begin to test packages for me too (hang), but I was able to use it and install from it without problems.
So you can test with it.

Following the failure of my Novatech-supplied defective MSI-G33M board, with mis-matched RAM, I have got a GA-G31MX-S2 to work with better RAM, able to at last install and run Ubuntu 7.10, to find that after mild over-clocking of its E2160 Core2 CPU, Gutsy can suffer from 'glitches', lock ups or even failure to boot in a way that is being reported more and more as a problem. on the MicroMart Forums and similar to my earlier board problems.
There are slight differences in the way that LinuxMint 4.0 performs, ostensibly using the same kernel, yet it is being reported as loading via DVD drives, running in RAM and then Installing more reliably than Ubuntu 7.10.
I shall therefore be checking the Alpha releases on my GA-G31MX-S2 based machine with slightly higher over-clock to see whether the Alpha releases are more tolerant, reporting the achieved functionality.

Having set the machine up as a Linux test bed, with XP-hosted SelfImage-121 for Linux partition imaging, I can restore any distro evaluation within a few minutes, making the whole process a lot easier and allowing quite prompt Ubuntu 7.10 restoration. (I have allocated 10GiB for the main partition at the beginning of the drive and a 1GiB Swap 'logical drive' a further 24 Gib 'down' the drive. The machine is set up for multiple boot of Ubuntu, WinXPhomeSP2 (OEM) and WinVista 32-bit Home Premium (OEM) (on a second separate drive), with start-up selection via auto-installed GRUB.

I'm closing this bug report as we haven't heard back from you with regards to testing Hardy and the 2.6.24 kernel with your setup.

That's OK as the new Kernel(s) seem to be much better
and I can't repeat the problem with my new MainBoard.
Sorry that I didn't actually request closure earlier.
Meanwhile, largely thanks to Updates, Hardy Alpha-5 is
getting better and better, whilst Alberto Molino's Envy is
also getting better and better, providing essential graphics
enhancements and better graphics drivers than limited stock !
