Hmmm.
Few things needs to be verified:
Is your reiserfs root partition 3.5 or 3.6 format? (can be checked in /proc/fs/reiserfs/.../version
Try to boot of different media (rescue disk/CD) and run resiserfsck on your root partition,
is there any errors? If yes - then fix them (with reiserfsck --rebuild-tree probably),
and try to boot off your root disk again.
Remember to read FAQ entry on reiserfsck --rebuild-tree on namesys.com web site.

Ok, so it is this code in _get_block_create_0:
        if (!is_direct_le_ih (ih)) {
            BUG ();
        }
Hm.
Is your root partition big?
I want to look at it is that's possible.
At least at the metadata (reiserfsutils contains tools to extract metadata from disk drive,
if you'd extract such metadata and send it to me before you run reiserfsck - that would be great)

Thank you.

Bye,
    Oleg

It's 3.6 format.

  # cat /proc/fs/reiserfs/version 
  ReiserFS version 3.6.25 [built into kernel]
  # cat /proc/fs/reiserfs/*/version
  new format      with checks off
  new format      with checks off
  new format      with checks off
  new format      with checks off
  new format      with checks off

I've tried reiserfsck with booting from spare root partition
formatted with ext3.  But there was no errors.

> Is your root partition big?

Yes.  It's 85GB.  And it's on a software raid (raid0) partition.

Hm. You said you are running 2.4.17-rc2, this is output from older kernel.
Or do you mean it is only 2.4.17-rc2 that cannot remount root read-write?

Hm.

Ok, I still want the metadata from this partition (read man on debugreiserfsck on -p option),
and tell me you reiserfsutils version.

Also were there any reiserfs specific error messages prior to the oops?

Yes, the cat output was from 2.4.16.  Kernels before -rc1 can remount
this root partition without errors.

Ok, I'll try that tomorrow.

There was no error message from reiserfs.

Thank you.

Good night, then.

This is suspicious, because there is reiserfs_warning call in call trace you've sent us.

Same problem here, but fixed with reiserfsck --rebuild-tree ...

> Is your reiserfs root partition 3.5 or 3.6 format? (can be checked in
/proc/fs/reiserfs/.../version

Mine is 3.6.26 but I don't have that info in my proc...Show info not
compiled in kernel

Did so and found errors

Ran  reiserfsck --rebuild-tree and system now boots


> Is your root partition big?

No,  4GB
