Bug#417087: madwifi-source: module load problem with 2.6.20

[Anders Boström]

Package: madwifi-source
Version: 1:0.9.2+r2156.20070225-1
Severity: important

After upgrade to 2.6.20.2 and madwifi 1:0.9.2+r2156.20070225-1, my
computer hang during boot, at module load of the madwifi modules.

Ctrl-C breaks up the hang, but X fails to start after this.

If I disable loading of the madwifi-modules during boot, the system
boot fine.

'modprobe ath_pci' hangs, and Ctrl-C don't work. kill of the
khelper-started modprobe-process breaks up the hang.

I can get the madwifi-driver working by this sequence:

# modprobe wlan
# insmod /lib/modules/2.6.20.2/kernel/drivers/net/ath_hal.ko
# insmod /lib/modules/2.6.20.2/kernel/drivers/net/ath_rate_sample.ko
# ifup ath0

modprobe of ath_rate_sample or ath_hal tries to load ath_pci and
hangs. This is strange as neither ath_rate_sample nor ath_hal is
dependent of ath_pci according to modinfo.

If seems like ath_pci fails due to missing ath_rate_sample when I run
'modprobe ath_pci' without prior manual load of ath_rate_sample, see
dmesg output below.

debugging this.
