2.4.20 Oops (semms in reiserfs)

working a while in X i got these errors (second error repeating for some time, i was able to use SysRq to sync, mount ro and reboot). seems to be related to reiserfs.

please cc me because I'm not subscribed to the list.

thanks,

daniel

the kernel is tainted due to the pwcx-i386 module foir the usb webcam and the modules for the conexant softmodem driver, both do not seem to be related to the filesystem.

below is the original oops and what ksymoops did from it.

Hello!

This looks like as if you have some memory corruption that is not reiserfs related, it is just reiserfs was unfortunate to call the kmem_cache_alloc() that stepped on the corrupted pointer. (and how the pointer got corrupted is not clear). And you can see, there was another non-reiserfs related caller that stepped on that same bad pointer in kmem_cache_alloc() too (only a bit later).
Perhaps you want to run memtest86 for some time to see if your memory is ok. And to run without binary modules loaded to see if they are the reason for the problem.

Bye,
Oleg
