| |
Hi.
I have a problem with 3c59x network driver. After some time (now it happened after 6 days of uptime) the card stops transmitting packets. Interrupt counter increments, the card recieves and trasmits some buffers, but the more time, the less packets are trasmitted and in the end it stops trasmitting at all. I don't know how to debug this, rmmod and modprobe of the module back helps to solve this for some time.
What kind of info should I post and how to track this nasty thing down? Note, that this is server and hence things like bisecting is no-go for me.

I know, that I have disabled APIC, I noted it yesterday and rebuilt the kernel with the APIC support, but still didn't reboot. If this is required I'll do so, but before that, there was running smp kernel and that kind of hangs appeared too.
There is nothing significant in dmesg, 2.6.17-rc5 was fine, so this is definitely a regression.
