Hi,
I'm experiencing a strange problem with a via rhine network card on Ubuntu 7.04 (2.6.20-16-generic #2 SMP). The hardware seemed to come into an inconsistent state, since rmmod'ing and modprobe'ing the via-rhine driver back didn't help.
After the problem had appeared, I could see the following in dmesg:
[ 8601.971189] irq 21: nobody cared (try booting with the "irqpoll" option) [ 8601.971214] [<c01543a4>] __report_bad_irq+0x24/0x80 [ 8601.971229] [<c015465e>] note_interrupt+0x25e/0x290 [ 8601.971238] [<c01538d0>] handle_IRQ_event+0x30/0x60 [ 8601.971245] [<c0154f91>] handle_fasteoi_irq+0xc1/0xf0 [ 8601.971252] [<c0105b70>] do_IRQ+0x40/0x80 [ 8601.971259] [<c0104233>] common_interrupt+0x23/0x30 [ 8601.971269] [<c01012b6>] mwait_idle_with_hints+0x46/0x60 [ 8601.971276] [<c0101409>] cpu_idle+0x49/0xd0 [ 8601.971289] ======================= [ 8601.971291] handlers: [ 8601.971293] [<f887ff10>] (usb_hcd_irq+0x0/0x60 [usbcore]) [ 8601.971311] [<f88a7dd0>] (rhine_interrupt+0x0/0xb80 [via_rhine]) [ 8601.971324] Disabling IRQ #21 [ 8637.970985] NETDEV WATCHDOG: eth0: transmit timed out [ 8637.971135] eth0: Transmit timed out, status 1003, PHY status 786d, resetting [ 8637.971163] via-rhine: Reset not complete yet.

The interrupt seemed to be unhandled and got disabled by the kernel then. The transmission seemed to time out for some reason (probably, the hardware got into an inconsistent state?).
Some related information:
kuvkir@coreduo:~% lspci |grep -i rhine 00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 7c) kuvkir@coreduo:~% uname -a Linux coreduo 2.6.20-16-generic #2 SMP Thu Jun 7 20:19:32 UTC 2007 i686 GNU/Linux kuvkir@coreduo:~% dmesg|grep rhine [ 2.982700] via-rhine.c:v1.10-LK1.4.2 Sept-11-2006 Written by Donald Becker
Is that information sufficient for debug? Let me know if you need any additional data.
