SubjectProblem in 2.4.28-rc1 with e1000 and io-apic
Hello,

I've got problems with a bi-xeon based on Intel E7320 chipset
with 2.4.28-rc1. When I boot the smp kernel, IO-APIC works fine
for all devices except for both e1000 lan.

e1000 driver reports on dmesg "watchdog tx errors".

I suppose it is an io-apic problem:
# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
0: 38000646 0 0 0 IO-APIC-edge timer
1: 2 0 0 0 IO-APIC-edge keyboard
2: 0 0 0 0 XT-PIC cascade
4: 16 0 0 0 IO-APIC-edge serial
8: 1 0 0 0 IO-APIC-edge rtc
71: 0 0 0 0 none eth1
72: 0 0 0 0 none eth0
[...] ^^^^^^

The system can't handle the lan interrupts. It should be the problem.

Enable or disable NAPI option for e1000 doesn't resolve the problem.

But, when I boot the kernel with "noapic" option, both lans work fine:
# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
0: 1090980 0 0 0 XT-PIC timer
1: 235 0 0 0 XT-PIC keyboard
2: 0 0 0 0 XT-PIC cascade
4: 16 0 0 0 XT-PIC serial
8: 1 0 0 0 XT-PIC rtc
9: 15629 0 0 0 XT-PIC eth0, eth1
[...]

Maybe, there are devices that are not supported on this kernel and that
create this problem:

Is there a way to force type of interrupts for both e1000 lan on "IO-APIC-level"?
or maybe to find the bug?

Thanks in advance.
