Completely dead on resume (no caps lock, nada)

Completely dead on resume (no caps lock, nada)

[Brannon Barrett Klopfer]

Hello,

Sorry to bug the entire list with such a vaugue post, but I'm not sure what
driver/subsystem is causing this problem. I'm sure you all are sick of "My
computer won't suspend, what do I do?" posts, but...well, my computer won't
suspend...


It's a brand-new HP dv8000t laptop (Phoenix BIOS, latest version, core duo,
ahci/ata_piix [native/legacy]). Suspending (echo mem > /sys/power/state)
works fine, but upon resuming, absolutly nothing works -- backlight stays
off, caps/numlock, network, etc. all dead. I've also tried

# cat `which poweroff` > /dev/null # cache it, in case disk dies upon resume
# echo mem > /sys/power/state ; poweroff -f

but it still just hangs (i.e., seems the entire system is just...dead). I've
tried numerous patches from here and there, and tried both native (ahci) and
legacy (ata_piix) sata, and a kernel with as little support as possible --
no usb, ide, smp, module, preempt, etc. I won't flood the lists with other
info, but it's all at

http://www.stanford.edu/~bklopfer/wontsuspend/

I'd be more than happy to try patches/let someone ssh into my box if it'd
help (new, so nothing sensitive on it yet).

Thanks,
Brannon Klopfer

    If no one reports bugs, they don't get fixed.

    Pavel Machek <pavel@suse.cz> is the swsusp maintainer, and should
have been CC'd on this, otherwise he'll probably never see it.
Linux-kernel is a busy place. :-)

    I know Mr. Machek wants swsusp bug reports filed in Bugzilla at
http://bugzilla.kernel.org , so you should do that, and then send a
follow up to this, CC'd to Pavel, with a bugzilla bug number.

CC'ing Rafael J. Wysocki <rjw@sisk.pl> as well probably wouldn't hurt.

Actually I probably would see it, just a little later.

Also I'm maintainer for swsusp. I tend to look after s2ram, too, so
cc-ing me will not hurt, but I do not maintain it.

Best place to ask is probably suspend-devel mailing list at
sourceforge's suspend project.

Actually I prefer 'simple' bugs to go via mail to suspend-devel... and
keep bugzilla for 'interesting' issues.
