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