Description Markus Hitz 2001-06-26 22:03:41 EDT

From Bugzilla Helper:
User-Agent: Mozilla/4.51 [en] (X11; I; Linux 2.2.5-15 i686)

Description of problem:
Fresh install of RedHat 7.1 on a system with two  AMD PCnet/Fast 79C971
based NICs.
On boot, the module is "loaded" (0 pages), but networking won't start.
After executing
"ifup eth0" and/or "ifup eth1" the respective NIC will show up twice in
/proc/interrupts
(the "ifup" command returns errors, the driver won't start).

Finally - after a clean boot - I did

rmmod pcnet32
modprobe pcnet32 (no action)
insmod pcnet32  results in kernel oops

and after

cat /proc/interrupts

the kernel hangs


How reproducible:
Always

Steps to Reproduce:
1. boot
2. rmmod pcnet32
3. modprobe pcnet32
4. insmod pcnet32

Actual Results:  kernel oops

Expected Results:  pcnet32 module gets loaded

Additional info:

A search on google turned up a few posts on the kernel list.
The problem also exists in the 2.4.3 kernels.

Comment 1 Arjan van de Ven 2001-06-27 04:15:48 EDT

The 2.4.3-12 kernel update we released should have this fixed. Could you
try this ? (yes I know it's hard to install without network)

Comment 2 Markus Hitz 2001-07-02 15:27:40 EDT

Problem resolved in 2.4.3-12 kernel.

Over the weekend, I swapped the pcnet NICs for cheapo RealTeks,
downloaded the latest RPMs from the GaTech mirror, and upgraded
the kernel. After successfully starting the new kernel, I re-installed
the pcnet cards. Kudzu did the rest.

Thanks.

Thanks for confirming this. I'm marking this as "fixed in errata" now.
