Summary: ksoftirqd load system, kernel hang after a few minuts
Kernel Version: 2.4.20-2.4.22
Status: NEW
Severity: blocking
Owner: other_other@xxxxxxxxxxxxxxxxxxxx
Submitter: dav@xxxxxxxxx
I've just seen something similar with official 2.4.20+e1000 v5.2.30.1
on a Dual Intel Xeon CPU 2.6G+hyperthreading. Note I use IRQ affinity
so both ksoftirqd_CPU[02] are at 100%.
The following is repeatable in about a minute which is good.
I send in around 700,000 packets per second on each of 2 interfaces,
and let the packets continually overflow the (4096 entry) buffers.
After about a minute I can't receive any traffic, and a couple
of occasions the machine just rebooted, so something is getting
corrupted. I was suspecting the e1000 driver buffer management until
I seen this?
Pádraig.
