x86-64 2.6.22-rc2 random segfaults

[Ioan Ionita]

Hello,

Since upgrading from 2.6.21 to 2.6.22-rc2, I started seeing some
segfaults in dmesg.
2.6.22-rc1-git2 even locked up on me at one point.

I'm using SLUB. I haven't yet found a way to easily reproduce the
problem.. Once I do, I'll try a git bisect

Hmm, nothing comes to mind. Please bisect.
