Unable to handle kernel NULL pointer dereference at 0000000000000001 RIP

Unable to handle kernel NULL pointer dereference at 0000000000000001 RIP

[Andreas Moroder]

Hello,

our SLES production system
2.6.5-7.252-smp #1 SMP Tue Feb 14 11:11:04 UTC 2006 x86_64 x86_64 x86_64
stopped with the following messages in the log
Is this a known bug in this version and is it solved in the next versions.

As I wrote it is a production server so I can't change away from reiserfs.

Thanks
Andreas Moroder

Hi,

this is vendor-provided kernel, so this is pretty much offtopic on lkml -- 
please file a bugreport in Novell bugzilla, which is a proper place for 
this.

Thanks,
