Opss! on 2.5.6 with ReiserFS

Opss! on 2.5.6 with ReiserFS

[system_lists]

[-- Attachment #1: Type: text/plain, Size: 1711 bytes --]


Hi there,

    i got a 'Opss' on my PII (one of my fileservers) just changing the 
kernel version from 2.5.5 to .6

The problem is got just in the first fsck (of a ReiserFS fs) on boot-time. 
This fsck is done to /dev/sda1 so raid1->ReiserFS is not the problem  (its 
just on the second place of the partitions to mount).

Any ideas?

Thanks by advance and sorry by the pour english.

Re: Opss! on 2.5.6 with ReiserFS

[-- Attachment #1: Type: text/plain, Size: 2970 bytes --]

Hi,
I have a very similar Oops while mounting my ReiserFS root partition with 2.5.6
2.5.5-dj3 and 2.5.6-pre2 are working
If necessary I can handcopy the Oops

Bye
