Title:
With a -pae kernel, freeze during boot when wistron_btns loaded
Status in The Linux Kernel:
Confirmed
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
With my Amilo M7400 and the recent Precise kernels (at least
3.2.0-[10-12] I think), the system freezes during boot with the Ubuntu
logo and colored dots on screen (the dots stop progressing), when I
have wistron_btns enabled in /etc/modules. I need wistron_btns on this
laptop for the wireless to work, which is why I'd like to have it
enabled.
This is unrelated to Bug #926007 which I also just filed: the
wistron_btns freeze happens even when I'm using fbdev. (With -intel,
the #926007 panic and this freeze take turns in who gets to mess with
me.)
From what I've gathered so far, it seems that wistron_btns works fine
if I manually modprobe it from my desktop, after booting without it.
So that's a workaround at least.
I can kill the freeze with Alt+PrtSc+REISUB. I'll provide any
additional info needed, though I don't know how to produce logs when
the system is frozen.
