Hi!
still experimenting with the resume from suspend on the Fujitsu
S6010. I can, however, still create a kernel oops. The kernel source
comes from alm_fixes5, kernel 3.15.0-rc7+. For that, do the
following:
1) Shut down X,
2) Unbind the consoles:
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo 0 > /sys/class/vtconsole/vtcon0/bind
3) Remove the i915
rmmod i915
4) Suspend the system
pm-suspend
Does it also break with plain echo mem > /sys/power/state?
No. If the modules stay resident, any user driven shutdown/resume events
by writing into /sys/power/state work just fine.
Does it break when you don't suspend at all?
No. Unloading and reloading i915 under normal conditions also works fine.
5) Resume the system by pressing on the power-button.
6) Reload the i915 module with
modprobe i915.
Result is a kernel-Oops:
Sounds like problem in suspend/resume framework, actually :-(.
Good guess, but wrong. The BIOS leaves the 830GM in a state the i915
does not seem to like.
Greetings,
Thomas
