Interestingly, I have just discovered that I can do the following on this machine *without*
locking it up (on Linux 2.6.23.9):
# cat /sys/bus/pci/devices/0000:00:0e.0/enable
0
# echo 1 > /sys/bus/pci/devices/0000:00:0e.0/enable
# cat /sys/bus/pci/devices/0000:00:0e.0/enable
1
where according to lspci:
00:0e.0 Network controller: Netgear MA301 802.11b Wireless PCI Adapter (rev 02)
Doesn't writing to this sysfs file also call pci_enable_device()? Loading the hostap_plx module is
still instantly lethal.
Cheers,
Chris
