    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:
