Hi,

I just bought a Netgear WG511 WLAN card. It should be supported according to
the "Supported Cards" page. Here the lspci -n output:

05:00.0 Class 0280: 1260:3890 (rev 01)

When I plug the card I get the following log entries:

  Dec  3 13:41:02 localhost cardmgr[1845]: socket 1: CardBus hotplug device
  Dec  3 13:41:03 localhost kernel: Loaded prism54 driver, version 1.0.2.2
  Dec  3 13:41:03 localhost kernel: latency timer: 0
  Dec  3 13:41:03 localhost kernel: DMA Memory support mask is 0xffffffff
  Dec  3 13:41:03 localhost kernel: prism54: pci_set_master(pdev)
  Dec  3 13:41:03 localhost kernel: PCI Memory remapped to 0x00000000
  Dec  3 13:41:03 localhost kernel: islpci_alloc_memory
  Dec  3 13:41:03 localhost kernel: islpci_statistics
  Dec  3 13:41:03 localhost kernel: eth1: loading firmware early at probe t=
ime as temporary workaround for broken device driver
  Dec  3 13:41:03 localhost kernel: eth1: uploading firmware...
  Dec  3 13:41:03 localhost kernel: isl38xx_upload_firmware(0xd08df000, 0x6=
d40000)
  Dec  3 13:41:03 localhost kernel: eth1: firmware uploaded done, now trigg=
ering reset...
  Dec  3 13:41:03 localhost kernel: isl38xx_interface_reset

After that I get a kernel panic which says the following:

  Unable to handle kernel NULL pointer dereference at virtual address 00000=
000
   printing eip:
  ....
  In interrupt handler - not syncing

The card it self seems to be working. The green led blinks slowly with
longer pauses and the orange led flashes.

This happens with kernel 2.4.23-rc3 and 2.4.23. I use Debian unstable on a
IBM ThinkPad T21.

Any comments what I can do to debug the problem?
