Good heavens.

Does it oops every time?  And does the oops trace always look like this?

dayum.  I cannot imagine how a susend/resume can cause a crash in
AF_UNIX code.  Which network device driver(s) are in use?

There are only 2 well known devices Realtek8139 and Intel 2200BG
Only explanation I have is that copy in resume copied in bug/random/accidentionally some memory part to unix socket kernel part memory??

Direct-rendering manager: the thing which does accelerated 3d
in X.

Disable CONFIG_DRM in your .config.

I got it again:
Tested your suggestions to switch off 3D acceleration, but without success.

Can you please try with a newer kernel, preferably 2.6.23-rc2?

Or 2.6.23-rc4?

Just did it - still same issue, but rarely

Can you attach your current .config, please?

Created attachment 12850 [details]
config.gz 2.6.22.X

config.gz 2.6.22.X

Can you try with CONFIG_NO_HZ unset, please?

Hi, no change :(

Can you unset CONFIG_DRM in turn and retest?
