| |
Hi,
I have one HP DL 140 G1 running with Debian stable and a locally-built, vanilla kernel. With 2.6.25.11, everything is fine.
But, after updating to 2.6.26.2, I noticed that pinging the host on the local ethernet sometimes (e.g. several times a minute, but not always) results in a round-trip time of larger than two seconds. The packets are not lost though, they're only severly delayed. For an ssh session to the host, this feels like somebody rocking a bad network connector. The same behavior is visible with 2.6.26 and 2.6.26.1.
Going back to 2.6.25.11 immediately fixes the issue for me.
Syslog doesn't say anything conspicious, unfortunately. As I don't have local access to the box, I cannot say whether it's only the network that freezes or whether it's the entire box.
Does it make sense to test any later 2.6.25.x kernel, or is there any post-2.6.26 patch available that may fix the issue for me?
Strangely, another DL 140 from the same charge runs just fine with 2.6.26.2.
Here is the output of lspci -vvv for the network interface:
