http://bugme.osdl.org/show_bug.cgi?id=2782
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@kernel-bugs.osdl.org
Submitter: dav@neocom.fr
Distribution: Linux/RedHat 9/x86
Hardware Environment:DELL PowerEdge-Dual Intel Xeon CPU 2.4G+hyperthreading
Software Environment:RedHat 9
Problem Description:when network flow is near 15 Mb/s bandwith, ksoftirqd loads
and kernel freeze after a few minuts
Steps to reproduce:
1. Boot system,
2. put linux system into 2 subnets,
3. generate 15Mb/s bandwith between to interface and wait for 1 hour
--- additional informations ---
This occurs with a lot of kernel tested (2.4.20, 2.4.21, 2.4.22, 2.4.22-ac4)
and with standard linux RedHat kernel up to kernel-smp-2.4.20-28.9.i686.rpm.
Datas collected when problem occurs :
# cat /proc/version
Linux version 2.4.20-8smp (bhcompile@porky.devel.redhat.com) (gcc version 3.2.2
20030222 (Red Hat Linux 3.2.2-5)) #1 SMP Thu Mar 13 17:45:54 EST 2003

When system is loaded (by process ksoftirq_CPU0), some datas are lost
(monitorring system reports
each 10 minuts CRITICAL alerts => 50% of warning report for packet lost).

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.

I've tried to use IRQ affinnity too, but without success, with or without.
I've tried to switch hyperthreading off into bios, without more success.
I've tried to deactive ACPI into bios too, problem is the same.

I've repeated this trouble with some NIC card. I've reproduced this with tg3
driver (Broadcom gigabit NIC), Dual Intel PRO/100S, tg2 driver and bcm5700
driver.

Ok, test in progress, and same problem occurs ;-(
I'm waiting for packet lost before to submit new informations into
ticket, do you want I collect some additional informations before to switch
our production traffic on another system ?
thx,
