------- Comment #54 from [EMAIL PROTECTED] 2007-12-04 16:18 -------
Hello,
I have a MSI l745 laptop that shows a 100% reproducible behaviour (phantom key
+ stuck keys), with a kernel 2.6.22 provided by Ubuntu and a kernel 2.6.24-rc4
(+ a hack in the hwsleep.c:acpi_enter_sleep_state - probably not relevant since
it happens with the ubuntu's kernel)
With the AC power adapter plugged, I see in dmesg:
[ 54.492465] power_supply ADP1: uevent
[ 54.492470] power_supply ADP1: POWER_SUPPLY_NAME=ADP1
[ 54.492477] power_supply ADP1: Static prop TYPE=Mains

isa0060/serio0).
[ 56.528136] atkbd.c: Use 'setkeycodes e071 <keycode>' to make it known.
Without AC, I see
[ 60.773379] power_supply ADP1: uevent
[ 60.773387] power_supply ADP1: POWER_SUPPLY_NAME=ADP1
[ 60.773393] power_supply ADP1: Static prop TYPE=Mains
[ 60.773397] power_supply ADP1: 1 dynamic props
[ 60.773401] power_supply ADP1: prop ONLINE=0
[ 60.789708] atkbd.c: Unknown key pressed (translated set 2, code 0xf2 on
isa0060/serio0).
[ 60.789716] atkbd.c: Use 'setkeycodes e072 <keycode>' to make it known.
[ 60.818902] atkbd.c: Unknown key released (translated set 2, code 0xf2 on
isa0060/serio0).
[ 60.818908] atkbd.c: Use 'setkeycodes e072 <keycode>' to make it known.
See how the keycode has changed with the online status. If I put back the AC
the keycode turns back to e071 again.
Booting with acpi=off or acpi=ht solves the issue.
The workarounds i8042.nomux=1, i8042.nopnp=1, ec_intr=0, ec_intr=2,
pnpacpi=off, removing ac/thermal/battery modules do not work in my case.
I also tried acpi=noirq, pci=routeirq without improvement.
I had a look in the FACS, the lock is always 0 (as are all the other fields, at
the exception of the version (01))
Also I can make the laptop go in sleep mode ("mem"), but it does not correctly
resume (the disk spins up, but the keyboard - i.e. the num lock - does not
work)
However it resumes fine if I make a "setkeycodes e071 255" before triggering
the sleep mode.
I will attach my dmesg... (I will try to do more tomorrow. It's a bit late
here...)
Hope it helps.
Regards
