Hello listers, Last night I upgraded one of the Linux guests used by our developers to kernel level 2.6.16.60-0.95.1-default. (Latest SLES10 SP4 kernel) By about 11:30 AM this morning, I was getting complaints from our developers that the system was hanging. Looking around, I saw that ksoftirqd was using close to 100% cpu.
Anyone got any ideas on what to check? I have looked in the archives, but they are a little old. The only messages I can find have to do with a hipersockets time out. Feb 9 11:21:39 bus0104 kernel: NETDEV WATCHDOG: hsi0: transmit timed out Feb 9 11:21:39 bus0104 kernel: qeth: Recovery of device 0.0.5100 started ...
