next in thread | raw e-mail | index | archive | help
Hello CURRENT,
I am running FreeBSD 8.0-CURRENT on a Dell E6400 laptop and I am
experiencing an IRQ storm on atapci. My dual-core ends up working at
about 40% CPU on interrupts. I have attached, uname -a, dmesg, vmstat
-i, top -S and my kernconf. The only changes made to the kernconf are
the ones described in /usr/src/UPDATING as to improve performance for
FreeBSD 8.x The reason I have for running CURRENT is that the my Dell
E6400 kern panics shortly after boot on FreeBSD 7.0-STABLE and on
FreeBSD 7.1-BETA2. A photo of a panic can be found below.
Thanks for any help regarding this,
Pontus Stenetorp
