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 transmission seemed to time out for some reason (probably, the hardware got into an inconsistent state?).
