Fedora 11: power-on the Broadcom BCM4312 WiFi causes kernel panic with system freeze after some delay

[Athmane Madjoudj]

Hello all,

I have Fedora 11 i386 with latest update, my system freezes after some
delay (about 3mn) with kernel panic, i have a HP Compaq 6730s
(freedos) with Broadcom BCM4312, i get the driver and firmware from
RPMFusion repo

kmod-wl-5.10.91.9-4.fc11.3.i586
broadcom-wl-5.10.91.9

When i power-off the wifi (from laptop button) the problem doesn't raise.

NB:
Before, i didn't have this problem on Fedora 10

Best regards.

The problem appear to be a driver bug, since when i reconfigured my
router with WEP (it was WPA2) everything is stable, no freezes or
kernel panics.

Good luck getting Broadcom to fix it...

Hopefully with a 2.6.31 or later kernel your BCM4312 device will work
without needing to use the "wl" driver.

is this chip is supported by bcm43xx or b43 kernel driver? (i tried
b43,i have extracted the propriety firmware to the right dir, but i
can't get it work.

Was "Hopefully with a 2.6.31 or later kernel" really unclear? :-)
Anyway, I was too optimistic -- the LP phy support doesn't appear
until 2.6.32...  In the meantime you may want to try using the
compat-wireless stuff:

Hth!
