Howdy,
My hp dv8000t (core duo) is completely dead on resume from RAM (no caps
lock, sysrq, netconsole,
nothing). I've tried a recent (2.6.18-rc4) kernel running almost entirely
naked, so to speak (~990K) -- no support for:
SMP
preempt
modules
networking (+ enet drivers, unless running netconsole)
USB and SATA (not at same time; rootfs is either usb drive or SATA [ext2/3])
FireWire
cpufreq
framebuffer (vga=0)
audio
PCMCIA
IDE (for cdrom)
I've tried both native SATA (ahci) and legacy (ata_piix), but same result
w/both -- completely dead on resume from RAM. Blindly entering commands
does nothing, and running "$suspend ; $shutdown" does nothing either. I've
also tried with and without noapic, and a number of other kernel
paramaters, but nothing seems to work.
Be more than happy to try out patches, etc. to get this thing working.
Additionally, if someone could point me to that "beep on resume" patch,
that'd be great.
First, please apply the appended patch and try the following:
(1)
# echo testproc > /sys/power/disk
# echo disk > /sys/power/state
This should turn off the non-boot CPU, freeze all processes, wait for 5
seconds and then thaw the processes and the CPU.
Works fine. FWIW, after applying the patchs (so as to have
2.6.18-rc3-mm2), my internal keyboard didn't work, so I used a USB one.
It could be my simple .config'ing error, didn't spend much time with it,
but know that I did use a USB keyboard, hence USB support in the kernel.
(2)
# echo test > /sys/power/disk
# echo disk > /sys/power/state
This should turn off the non-boot CPU, freeze all processes, shrink
memory, suspend all devices, wait for 5 seconds, resume the devices etc.
IOW it does everything that's needed for a suspend except for actually
suspending.
With *legacy* ata_piix, it works fine, as does a "real" suspend-to-disk.
It still *will not* resume properly from suspend-to-RAM, with and
without noapic. FWIW, somehow the built-in keyboard managed to get its
caps lock light on (I couldn't get it off again), and it *did* come back
on when the machine resumed from RAM, though nothing else (network, usb,
etc.) worked.
Using native ahci and the "test" suspend-to-disk, the system hangs. I
did this from init=/bin/bash with vga=794 (so I could see all output),
however, at least the last few lines match w/vga=0 (i.e., fb didn't
affect problem). The hand-copied (pardon any typos) output is:

# Hangs here. Screen blanks in maybe 5-10min, won't turn back on; I
assume this is the hardware doing something. Again, this is only with ahci.

I'll try to get that beep patch, to further diagnose things...
