I read this thread earlier in the week with a nagging memory of a friend
complaining about this card, so last night I tried it out with
yesterday's -current snapshot on a as-yet unused Vaio N505X. I'm seeing
some `interesting' behaviour, although I don't know enough about the
pccard stuff to pin it on anything in particular.

On boot, everything works fine (including repeated insertion and
removal). Ping-flooding the machine, systat -vmstat shows the IRQ
assigned to ep0 going wild as expected.

After an apm suspend, the card doesn't work properly although I see the
same

  ep0: <3Com 3C574B etc.> at port 0x240-0x25f irq 11 slot 0 on pccard0
  ep0: Ethernet address 00:50:04:fd:94:c9

and the media-select light comes on again. (I have PCIC_RESUME_RESET
turned on.) Pinging the machine from the network, packets get through,
but very slowly:

  # ping 192.168.64.3
  PING 192.168.64.3 (192.168.64.3): 56 data bytes
  64 bytes from 192.168.64.3: icmp_seq=13 ttl=255 time=911.308 ms

  64 bytes from 192.168.64.3: icmp_seq=19 ttl=255 time=851.989 ms
  [...]

systat -vmstat no longer shows any IRQ activity on the card's IRQ (or on
any other during a ping flood). If I then unplug the card and reinsert
it, the light stays off. Attempting to ping outwards from the Vaio locks
it solid immediately!

Any guesses what's going on here? Is this a known problem? I've put the
kernel config file and bootup dmesg at

  http://www.miranda.arachsys.com/3cfun/VAIO
  http://www.miranda.arachsys.com/3cfun/dmesg

for reference. Unfortunately I don't have any other pccards handy to try
in this machine, nor another available laptop in which to test the 374B.

Regards,

Chris.
