Description Jaraeez 2006-10-17 02:41:38 UTC
Description of problem:

I find that the system just freezes at no certain times in particular but would
say at least 1-2 times a week. I have been trying to figure out if it was during
anything in particular with regards to what I was doing at the time, but it is
intermittent. When it freezes then all I can do it hit the reset button to get
the system back up again. I noticed it while running kernel 2.6.17-1.2187_FC5
but still have these symptons (not crashed yet but log still shows same error)
once I upgraded to 2.6.18-1.2200.fc5.

Can't diagnose problems with binary modules loaded.

Hi thanks for the reply. Could you explain what you mean so that I can take this
further.

Cheers




Comment 4 Dave Jones 2006-10-18 04:11:39 UTC
It means you loaded some modules (from a third party) that we don't have the
source for, which tainted your kernel. Only the provider of those modules can
debug this situation, as only they have all the source code necessary.

Comment 5 Jaraeez 2006-10-18 21:57:07 UTC
OK thanks for the info. Do you know which thired party modules they are? So I
can investigate further. Are you referring to the ndiswrapper or nvidia as I
think they are the only two third party mods.

Cheers


Comment 6 Dave Jones 2006-10-18 22:22:58 UTC
Both.


Comment 7 Jaraeez 2006-10-24 14:21:27 UTC
OK thank you...
