Description of problem:
Fresh install of RedHat 7.1 on a system with two AMD PCnet/Fast 79C971
On boot, the module is "loaded" (0 pages), but networking won't start.
"ifup eth0" and/or "ifup eth1" the respective NIC will show up twice in
(the "ifup" command returns errors, the driver won't start).
Finally - after a clean boot - I did
modprobe pcnet32 (no action)
insmod pcnet32 results in kernel oops
the kernel hangs
Steps to Reproduce:
2. rmmod pcnet32
3. modprobe pcnet32
4. insmod pcnet32
Actual Results: kernel oops
Expected Results: pcnet32 module gets loaded
A search on google turned up a few posts on the kernel list.
The problem also exists in the 2.4.3 kernels.
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)
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 for confirming this. I'm marking this as "fixed in errata" now.
