During Easter I had time to test a bit more the patch and I found a very bad
issue between acpi keys, preempt and suspend. It's a lot of data; I have
filed the same data on the above bug.
Hi!
This is to report an issue with 2.6.11 and ACPI battery/ac. The resume is:
acpi battery with preemptive kernel do not work, while the same kernel with
no preempt works ok. I have tried to collect all the possible info; tell me
if you need something more.
The details:
The working kernel is 2.6.11 with the patch from the acpi-devel list to fix
acpi keys (not working otherwise). See for a description
http://bugme.osdl.org/show_bug.cgi?id=4124
The data on the non-preemptive kernel (boot messages, config, etc) is here:
http://www.dea.icai.upco.es/romano/linux/br/config-nop/laptop-config.html
This works, apart for the little glitch that doing two "acpi -V" at the same
time, one of them give "0" for battery charge, while the other works ok.
Suspend/resume works perfectly with this script:
http://www.dea.icai.upco.es/romano/linux/br/config-nop/rg_suspend_script_nowait
The complete configuration for the preemptive kernel is here:
http://www.dea.icai.upco.es/romano/linux/br/config-p2/laptop-config.html
The problem with the preemptive kernel is that after a while the ac/battery
ACPI reading stop working. The errors do occur at seemely random times.
First time it happened at boot, but I do not have a log of it. Second time
it happened at resume time, and I have captured "oops" (really, scheduling
while atomic) from this (in the following lines). After that, battery/ac
status does not work anymore. If you look at the following dmesg, battery
module will load but it will not detect any battery in the slots.
The same information as above, after resume, is here:
http://www.dea.icai.upco.es/romano/linux/br/after-res2/laptop-config.html
After that, I activated full ACPI debug (echo 0xFFFFFFFF >
/proc/acpi/debug_level) and tried to load again the battery module. This
time the loading suceeded. The full syslog output (it's enormous) is
here:
http://www.dea.icai.upco.es/romano/linux/br/after-res2/syslog.txt.gz
Notice that a very similar thing happens with vanilla 2.6.11 with preemptive
kernel (without the patch above). Notice, though, that the acpi key delay
bug is resolved by simpl activate preempt, like Mr. Shaohua said in
http://bugme.osdl.org/show_bug.cgi?id=4124#c8
Here is the "oops" log at resume (log starts at suspend time)
