I see the same problem. This is the lspci output:

05:09.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) 3f:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express

I think Chuck traced the text that comes out to 3Com, but its been a while. AFAICT, the problem started around the 2834 kernel/Feb 15.


The only seemingly relevant change I see in the 3c59x driver in the February time frame is this one, although the change appears harmless enough: http://lkml.org/lkml/2007/2/1/183

    NET-3c59x: turn local_save_flags() + local_irq_disable() into local_irq_save

    drivers/net/3c59x.c::poll_vortex() contains local_irq_disable() after
    local_save_flags().  Turn it into local_irq_save().

You might try reverting it to see if it helps.
