| |
Hi,
we have about 70 P4 uniprocessor machines (some with Hyperthreading capable CPUs) running linux 2.4.29, which are woken up on the weekdays by sending a WOL packet to them. The machines all have a E100 nic with WOL enabled in the bios. The E100 driver is compiled into the kernel and not loaded as a module.
If the machine which should be woken up is already running (because someone switched it on by hand), the WOL packet causes keventd to go mad and "use" 100% CPU:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2 root 15 0 0 0 0 R 99.9 0.0 140:50.94 keventd
This can be reproduced on any of the 70 machines by simply sending a WOL packet to it, when it's already running... No entry is made in the kernel log.
The dmesg of an affected machine can be found at: http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-dmesg Our kernel-config is at: http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-generic-config lspci -vvv is at: http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-lspci
We are using a kernel.org linux 2.4.29 kernel patched with the current autofs patch and ACL support.
