Francois (and any other interested parties on netdev):
I'm seeing a "hang" under 2.6.14.4 when the link goes up (I think) on a
Netgear GA511 PCMCIA gigabit NIC. I put "hang" in quotes because while
the system is generally unresponsive, Magic SysRq responds and I can
return the system to normal by ejecting the card.
I was able to get the following lspci -v output to identify the card:
0000:07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8169 Gigabit Ethernet (rev 10)
Subsystem: Netgear: Unknown device 5200
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11
I/O ports at 4800 [size=256]
Memory at d4000000 (32-bit, non-prefetchable) [size=512]
Expansion ROM at f2000000 [disabled] [size=128K]
Capabilities: <available only to root>
dmesg output from loading the driver is below; as you can see, I also
dumped a SysRq-P during the "hang":

For reference, I get substantially the same behavior and messages
under 2.6.12 (as shipped with Ubuntu Breezy). Under 2.6.14.4, if the
link is up during boot time, I additionally seem to get "BUG: soft
lockup detected on CPU #0!". I transcribed the messages by hand, but
since they're substantially the same as above, I haven't typed them in
here --- if anyone wants them, though, just let me know.
Any ideas? I'm happy to try patches, if anyone has any to offer. I'm
afraid networking and kernel programmin are both still a bit black-magic
to me, so I haven't tried any of my own in-code debugging yet...
Thanks in advance for any help. I'd certainly love to have Gigabit to
connect this laptop to my hopefully-soon-to-be-completed MythTV
box. :)
Happy New Year!
