Hi LKML,

let me forward this also to wider audience.

For me it dies somewhere in list_for_each_entry_rcu() which could
apply borked data - just my assumption.

Hi,

I receive the below attached general protection fault. Details:
1) HW: HP BL460c G6
2) Kernel: 2.6.37
3) Arch: x86_64

System is unusable and does not respond. Currently I'm trying to find
the way to reproduce this issue.
