Comment 1 Trever Adams 2011-07-05 19:44:33 UTC

I switched Realtek 8169 to Intel e100e PCIe card. I have not been able to duplicate any of these problems since, even under very heavy load. The process is also much more idle (nearly completely used w/ 8169 and about 30-70% idle most of the time, more than 50 quite often, with the later card).

I do not know if the 8169 chipset is just broken or if the driver is, but the problem lies with one of the two.

Comment 4 Josh Boyer 2011-09-26 17:56:08 UTC

Have you tried this card with the latest 2.6.40 kernel in F15?

Comment 5 Trever Adams 2011-09-26 18:46:13 UTC

I have not. I am afraid this is a production AMANDA backup server and I have switched to the Intel card as stated. I cannot take this machine down to do testing. I am sorry.

Comment 6 Josh Boyer 2011-09-26 18:58:54 UTC

Ok, that is perfectly understandable.  I'm going to close this bug out as insufficient data.  We haven't seen many other reports of it and we'd need it to happen on a fresh kernel anyway.  Thank you for taking the time to report.
