[ltp] I need some help on ACPI sleep -- NOW WORKING !!!

[JP Renaud]

hi,

the ACPI sleep problem on my R51 is now fixed. i noticed a hic-up in the dm=
esg=20
output regarding local APIC. i disabled this from the kernel (#=20
CONFIG_X86_UP_APIC is not set) and now it is working well. to be fair, i am=
=20
not sure why this was set in my .config as so many post seem to recommend t=
o=20
turn it off. mea culpa.

I even adapted the sleep.sh script that Andre sent me (commented out the=20
battery stuff) and linked it to an ACPI event (FN+F4 and LID) and everythin=
g=20
seems fine on resume now (USB, Network, sound ...)

thanks you very much all of you for all the pointers. very much appreciated.

with sleep and hibernate fully working now, the next on the list is=20
speedstep ;-)
