I should have reported this problem here first (rather than in lmkl)
It has been already reported on lkml by Brad Campbell (then forwarded
here by randy)
Don't know if it has something to do with the tcp bug that was fixed
for 2.6.9.
here is my original mail:
I've just experienced this oops too.
The kernel is a 2.6.10-ac8 and it doesn't seem this issue has been
fixed in 2.6.10-ac10 nor in 2.6.11-rc1 (sure I'd love to be wrong
here ;-) )
