SubjectRe: [Bug #13337] [post 2.6.29 regression] hang during suspend of b44/b43 modules
Date
Hi,

I'm not sure if I experience the same bug on my apple iBook G4 (ppc
7447A, altivec supported PowerBook6,5) or just something very similar.

With v2.6.30-rc1 I noticed, that suspending to ram does not work if my
wireless card is 'up'. The wireless card is an apple airport extreme
card, this is its lspci output:

0001:10:12.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)

I tested suspend like this:

# unload the wireless module
modprobe -r b43
echo mem > /sys/power/state
# wake up works fine

#loading b43
modprobe b43
echo mem > /sys/power/state
# wake up still works fine

ifconfig wlan0 up
echo mem > /sys/power/state
# the box does not wake up, I guess it's not really sleeping, because
# the sleep led is not on

I bisected this and got:

5bb644a0fd25a5e083ecbfaa92a211db99aa6ef7 is first bad commit
