Re: strange problem with LX
The scrolling rate is about 1 line per second. /proc/interrupts showed
the network card (DE500-BA) as having over 144 million interrupts. So, I
shut down the interface and removed the kernel module. voila, vmstat is
now reporting on the order of 1050 interrupts per second. So, just to see
what would happen, I reloaded the kernel module and fired back up the
interface. Result: the computer is working perfectly now. Thank you very
much. Now I have this question: every time I reboot this happens, is
there something to look for that might be causing problems with the
ethernet kernel module? Or is this likely not a kernel problem at all?
(hardware?)
Thanks again for the prompt help,
