Public bug reported:
I am using an HP/Compaq Presario C751NR laptop computer, with Ubuntu
8.10 x86_64 and Linux kernel 2.6.27-9-generic. I can suspend and resume
properly one time only. On the second resume, the lights on the keyboard
come on, but the monitor does not turn on and nothing happens.
Apparently, the processor is on, because the computer gets hot fast
without the fan.
I have tried disabling different modules, and I have tried various
graphics tricks (in case that is related to the problem), all to no
avail. I've looked over dmesg, and there are two lines reporting 'ACPI
Exception' and one reporting 'ACPI Error', but I have no idea where to
go from here. I will attach the output of dmesg before the first
suspend, after the first suspend, and after running 'sync; echo 1 >
/sys/power/pm_trace; /etc/acpi/sleep.sh force' as a second suspend and
rebooting when the computer freezes. I will also attach the output of
'sudo lspci -vnvn' and of 'uname -a'.
