Latest working kernel version:2.6.25-rc1

Earliest failing kernel version:2.6.25-rc2

Distribution:debian/etch

Hardware Environment:x86 + bcm4306 (14e4:4320(rev 03))

Software Environment:debian/etch + new kernel mentioned above+wpa_supplicant v0.6.0 (cvs as of 02/17/2008, compiled against 2.6.25-rc1-headers). Both compiled locally by gcc-4.2.3. (Kernel configuration and full output of lswh lspcicould be send on request, since there is no possibility to attach files here.)

Problem Description: When wpa_supplicant comes into play during init, the system freezes with the following messages:

"wpa_supplicant[2734]: segfault at 806de20 ip 806de20 sp bf8693ac error 4
Kernel panic -- not syncing: Aiee, killing interrupt handler"

After a few seconds (or else after pressing a key?) a new (unrelated?) message is added:

"atkbd.c: Spurious ACK on ISA0060/Serio0. Some programs might be trying access HW directly."

Steps to reproduce:

Try to connect via wpa_supplicant/WPA2 to an AP (which in my case is a WRT54GS V1.0 running openwrt on linux-2.4. Other models not tried.)


With 2.6.25-rc1 I already experienced the problem, that udev did not rename the wlan device to eth2, as previous kernel versions actually did (at least 2.6.23.11). I found the following workaround (within /etc/udev/rules.d/z25_persistent-net.rules). This may or may not have to do with the problem:

# PCI device 0x14e4:0x4320 (bcm43xx)
#SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:90:(censored)", NAME="eth2"
SUBSYSTEM=="net", DRIVERS=="?*", SYSFS{address}=="00:90:(censored)", SYSFS{type}=="801", NAME="wmaster0"
SUBSYSTEM=="net", DRIVERS=="?*", SYSFS{address}=="00:90:(censored)", NAME="eth2"
