forcedeth broken powermanagement/irq handling ?
Date: Sat Apr 15 2006 - 05:52:46 EST
I am runnig a 184.108.40.206 kernel on a DFI LP NF4 SLI-DR Expert mobo, which
has an nvidia chipset with onboard nic. The nic works fine with the
forcedeth driver, perfomance is ok (good). The system is a x86_64 FC5
install on a dual core opteron 170 cpu with 2GB (2x1GB in dual channel)
of Ram installed.
When I suspend the machine using ACPI S3 or swsup and resume it the
network is dead. I cannot recive an packages. ifdown / ifup does not
help. Restarting the network using /sbin/service network restart also
does not get network working. Unloading and loading the driver (modprobe
-r forcedeth;modprobe forcedeth) has the same result-> dead network.
I have to reboot in order to get the network working again. I have a
static IP so no dhcp issue.
This makes suspend useles on my box, because I have to reboot anyway to
get my network working.
What could be causing this? If there is any info that I can provide to
help fixing this bug tell me.
I also noticed this (don't know if it is related or not but doubt it):
0: 640968 628532 IO-APIC-edge timer
1: 4763 4745 IO-APIC-edge i8042
8: 0 0 IO-APIC-edge rtc
9: 0 0 IO-APIC-level acpi
14: 1552 1082 IO-APIC-edge ide0
15: 44443 44261 IO-APIC-edge ide1
16: 57625 44633 IO-APIC-level libata
17: 972904 0 IO-APIC-level eth0
why does all interupts of eth0 (forcedeth) goes to cpu 0 and never to 1
? irqbalance is running.
