Kernel panic with live CD on Thinkpad 600e

Ubuntu->kernel as error is a kernel panic

I am presuming this is the live CD

Can verify this on Thinkpad 600E, Pentium II, 196 MB RAM. Memtest86+ passes. Detailed message is:

[33.046765] invalid compressed format (err=2)
[33.052965] Kernel panic - not syncing: VFS: Unable to mound root fs on unknown-block(1,0)
[33.053090] _

Install CD btw. happens in normal and safe graphics installation mode.

Yes. I just downloaded it from the Ubuntu site. I also tried Xubuntu and got
the exact error as above.

Hi all,

I am not sure how Ubuntu's bug reporting system works but the bug I posted
states that it is unconfirmed. I recieved the email below from another user
with the same issue. Thanks for your help.

Kernel panic with live CD on Thinkpad 600e
https://launchpad.net/bugs/68720

Same problem confirmed on 600e however ubuntu-server 2.6.17 kernel works fine to boot( sound/apm/acpi/suspend and other problems exist ).

I Used the server cd to install, and then apt-get kubuntu-desktop.

Got the sound to work using regular module param magic found on google.

But now, I cannot suspend, well suspend works, but resume crashes box (auto-reboot).

I tried compiling older kernel (2.6.12.6) but this kernel will not boot ( same problem as described above. )

Anyone knows what is different in server kernels?

This 600E as run an old debian system ( don't know which..) and fedora 3 for a while using 2.6.9 or 2.6.10 kernels.

Hi,

I have the same problem with thinkpad 600X with 192M of memory.

My whole context is
   thinkpad 600X
   thinkpad T30
   ubuntu i386 7.04 Desktop
   kubuntu i386 7.04 Desktop
   mandriva 2007.1 One Free KDE

I can install three CD on T30
I can install mandriva on both laptops

Launch of kubuntu stops just after
   loading initrd.gz .........
   (clear screen)
   invalid compressed format (err=2)
   -- System halted

Launch of ubuntu goes more and says :
   ...
   [44 ...174] RAMDISK: Compressed image found at block 0
   [45 ] invalid compressed format (err=1)
                      VFS: Cannot open root device "<NULL>" or ....
                      Please append a correct "root=" boot option
   [45 ...190] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(104,1)
   [45 ...282]

(note : the laptop having a faulty screen I cannot give the numbers at head of messages :-( )

There are a difference at launch between mandriva and ubuntu.

ubuntu on 600X gives messages :
  ....
  [43 ...202] EISA: Probing bus 0 at eisa.0
  [43 ...284] Cannot allocate resource for EISA slot 1
  [43 ...367] Cannot allocate resource for EISA slot 4 (note : there aren't slots 2 and 3)
  [43 ...457] EISA: Detected 0 cards.
  ....

dmesg on T30 with ubuntu gives :
  ....
  [ 29.630209] NET: Registered protocol family 16
  [ 29.630344] EISA bus registered
  [ 29.630351] ACPI: bus type pci registered

  [ 30.887464] Cannot allocate resource for EISA slot 2
  [ 30.887467] Cannot allocate resource for EISA slot 3
  [ 30.887470] Cannot allocate resource for EISA slot 4
  [ 30.887473] Cannot allocate resource for EISA slot 5

  [ 30.887481] Cannot allocate resource for EISA slot 8
  [ 30.887483] EISA: Detected 0 cards.
  ...

There are no EISA messages at mandriva's launch

Is it possible to launch (k)ubuntu without EISA probing ?

Thanks for your attention

Jacek

It works with ubuntu 7.04 alternate i386.

EISA messages are there in dmesg, so EISA isn't the reason of the problem.

Conclusion : I have no more the problem, but ubuntu has.

Jacek

FIXED in 7.04, used alternate CD, install went very well.

Sound still broken ( but I think the same module param magic will work)

Also booted fine from updated kernel ( after apt-get upgrade)

suspend/resume also working fine.

thanks!

Setting this to Fix Released based on the last comment.
