Public bug reported:
Ubuntu 8.10, upgraded through Intrepid Alphas to current. Similar laptop
on fresh intrepid install exhibits same behavior.
ACPI in intrepid seems to be broken for my HP Compaq C712NR laptop.
Some stuff is just broken after a suspend/resume, some are broken all
the time.
Broken all the time:
Fan speed is an all or nothing, so it heats up to way hotter than it
normally should, then is on for 5 seconds at full speed, off for 5
seconds. In Hardy, fan was an average 1/3(ish) speed unless I was doing
something CPU intensive.
Broken after resume from S3 (Suspend to RAM):
Resume from S3 a second time fails (No attempt to load, just black
screen, no hard drive activity).
ACPI cannot find battery after S3 resume ("[ 8422.812268] ACPI: Battery
Slot [BAT0] (battery absent)" in dmesg during the resume)
ACPI cannot detect an AC adapter after S3 resume. Probably connected to
the battery issue above, after resume ACPI does not detect a AC power
source. (I'm confused at what ACPI thinks is powering the computer at
this point)
Attached is tarball of /proc/acpi after a resume, working /proc/acpi to
come later (After I reboot).
