Today i got a chance to try fc6test1 and I encountered the same kernel panic.
This time due to the lockdep feature in the new kernel i got a ver nice verbose
output that i feel would help out this bug to.
Test kernels w/ e1000 7.1.9-k4 are available here:
Please give those a try and post the result here...thanks!
During a 24hour hour test period I experienced no kernel panics. I did however
loose 1 of the 2 interfaces sometime between hour 7 and hour 24. I have looked
thru /var/log/messages and have not seen anything to say why it was no longer
configuring an ip on eth0. I had no errors or anything else out of the ordinary
when I did ifconfig -a.
Is there any other data I could provide you from the system?
Can you bring-up eth0 manually now? Or is it completely dead?
Yes it can be brought up manually, with dhclient or with the script. It is not
Ran the stress test script overnight and this time in a 24hour period everything
worked fine. I belive someone may have mad some adjustments to the machine for
the first test cycle causeing the interface to drop. This time everything was great!
Hmmm...so does that imply that this issue is resolved? Or that it never was a
real issue? Or...?
No this was/is a real problem. The 7.1.9-k4 e1000 drivers seem to do the trick.
This actually happens on Fedora 5.90 (Core 6 test 1) also.
