Probably TX timeout routine should reset more things. ifconfig down up makes it run again.
BTW. I am getting sometimes the following messages:
Mar 13 18:58:54 crds kernel: Uhhuh. NMI received for unknown reason 3c. Mar 13 18:58:54 crds kernel: Dazed and confused, but trying to continue Mar 13 18:58:54 crds kernel: Do you have a strange power saving mode enabled? Mar 13 20:34:15 crds kernel: unexpected IRQ vector 208 on CPU#0! Mar 15 10:23:12 crds kernel: unexpected IRQ vector 208 on CPU#1!
This I am seeing rarely: Feb 28 10:55:47 crds kernel: lockd_up: no pid, 2 users??
Mar 15 13:33:40 crds kernel: lockd_up: no pid, 2 users??
This messages occure when the driver hangs: Mar 17 16:43:18 crds kernel: eth0: transmit timed out, Tx_status 00 status 2019 Tx FIFO room 3068.
This message does not cause the hang: Mar 13 13:51:48 crds kernel: eth0: transmit timed out, Tx_status 00 status 2000 Tx FIFO room 3068.
Another ones:
Feb 22 20:30:29 crds kernel: Uhhuh. NMI received for unknown reason 2c.
Also the problem with HDIO_UNREGISTER_HWIF is not fixed. I need to exercise the newly registered and mounted disk a bit (running updatedb is usually enough). Then I umount, sync, and call f = open("/dev/hda", O_RDONLY); (may be I should open /dev/hdc here?). i = ioctl(f, HDIO_UNREGISTER_HWIF, 1); (1 corresponds to hdc). The system hangs in 0.1 s to 0.5 s to few seconds to few minutes after without a warning.
