Hi Lee,

But unloading all vmware modules should be good enough ? And how about
the binary module of nvidia ? It's active ofcourse else i'd not be able
to use all the features i normally use.

Eitherway, several kernels back also made no difference for this issue.

So right now, i'm leaning on the experience i have with working with
this system and trying to isolate things i suspect, before i go to more
radical steps :)

And again, under windows 2k server, xp pro, redhat enterprise and
freebsd i never had these issues.
