ATA error. seems VIA 6421A RAID card related

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description does not yet have enough information.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

Reposted as a kernel bug by request:
Seems to be related to bug #125832, in that it only affects the two machines that needed wireless drivers, and not the three others I installed the new kernel on.

Kernel freezes 1/3 through boot on my Toshiba Satellite 4600 with
kernel -13 Ok with the previous kernel, except for the missing
wireless driver. Booting the -13 rescue from the grub menu freezes with
a register dump - would this be in a log file anywhere so I could post
it?

Also freezes on my generic old P3-800/512 Ram system with a linksys USB
wireless card. Two other PCs (one P3, one P4 and Amd-64) are ok with
the new kernel. The need for a wireless driver seems to be the common
factor between the laptop and the other PC that borked in exactly the
same manner. Confirmed that both hung PCs boot ok when I step back to
the last working kernel, which was in one of the two cases 2.6.22-12.
The 2.6.22-13 kernel barfs on on affected systems even in rescue mode, you
have to step back to the last kernel.

I will post the results of the tests you requested from the other tester this evening.

Last thing seen on the screen when I boot normally:
Typed by hand, I will try not to make mistakes:

I obviously ran this on the -12 kernel, since the -13 kernel borks on startup:
uname -a:
Linux Lenneir 2.6.22-12-generic #1 SMP Sun Sep 23 18:11:30 GMT 2007 i686 GNU/Linux

I assume the bad kernel would give the same info except with -13 replacing -12?

ok, when i was installing a new ubuntu 7.10 i met the problem again.

anyway i found the problem!

after i plug out my RAID card, it works! and boot into the system! works fine!

my RAID card is: VIA 6421A PCI-IDE/SATA RAID card, on which there are 2 IDE harddisks.

hope this could be useful!!

Hi MeteorRain,

The Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks

Hi Ogasawara-san:

I boot into ubuntu 7.10 without my raid card, and upgrade my system to 8.04 beta, and it works with my card!

Many thanks to you!

Doitashimashite :) I'm going to mark this as fix released against the Hardy kernel. Please feel free to reopen if you notice any regressions. Also please continue to report any future bugs that you may find, we really do appreciate it. Thanks!

I seem to be having a similar problem.

I'm trying to install Ubuntu Hardy 8.04 on a new disk using the LiveCD. The LiveCD only gives a few errors that look like the ones above giving "ATA7.00: Emask error..."

I run Ubuntu Gutsy on this system fine and I will give the diagnostic info running from this partition:
