Hi there,
While testing for a different issue on a box with two e100 NICs I noticed
that interrupt and other accounting are accumulated to the first e100 NIC.
Tested 2.4.(29|30|31|32)-hf32.1 plus 2.4.33-pre1 so the issue has been in
there for a while :(
e100 is compiled as module, the problem is not there with 2.6.15.
The problem also goes away if I compile e100 in, tested with 2.4.32-hf32.1
grant@deltree:~$ while true; do egrep 'eth0|eth1' /proc/interrupts; sleep 1; done
11: 3407 XT-PIC eth0
12: 630 XT-PIC eth1
11: 3436 XT-PIC eth0 [same test as below]
12: 921 XT-PIC eth1
11: 3439 XT-PIC eth0
12: 1266 XT-PIC eth1
11: 3443 XT-PIC eth0
12: 1343 XT-PIC eth1
11: 3446 XT-PIC eth0
12: 1343 XT-PIC eth1
11: 3449 XT-PIC eth0
12: 1343 XT-PIC eth1
11: 3456 XT-PIC eth0
12: 1343 XT-PIC eth1
dmesgs + configs on http://bugsplatter.mine.nu/test/boxen/deltree/
Is this a known issue?
Cheers,
Grant.

part of http://lkml.org/lkml/2006/1/9/27 -- watching interrupts on
eth1, but they're being accumulated to eth0:
grant@deltree:~$ while true; do egrep 'eth0|eth1' /proc/interrupts; sleep 1; done
11: 9136 XT-PIC eth0 \
12: 4 XT-PIC eth1 |

12: 4 XT-PIC eth1 / sys 0m0.200s
11: 10321 XT-PIC eth0
12: 4 XT-PIC eth1
Odd, with 2.4, the two e100 NICs are not being accounted properly:
