Harddisk problems after S3

Harddisk problems after S3

[Alberto Piai]

Hi everybody,

the first part of the story is at
http://bugme.osdl.org/show_bug.cgi?id=3586

After removing the pushl $0 line in wakeup.S i got a successful resume, and with vbetool the screen was back to life. Had to boot whit vga=normal and unload all modules to get this, will try later to find the showstopping module.

After the resume, when trying to do anything with the disk (like unmount a partition) i got this:

hda dma_timer_expiry: dma status==0x21
hda: DMA timeout error
hda: dma timeout error: status=0x58 {DriveReady SeekComplete DataRequest}
ide: failed opcode was: unknown

each line came 15 or 20 seconds after the other, and the whole repeated 4 times. then i got the bash back and everything looked fine.... then when i rebooted it crashed...!!

Maybe this should be discussed togheter with people from other mailing-lists? can somebody point me to the appropriate address?

Thanks,
Alberto

Ask ide maintainers...

The fact that we do nothing with the _GTM, _STM and _GTF methods doesn't
help here. Implementing those ought to help on a range of IDE resume
issues.

Hi,
[Send this to the ide maintainer to seek his help]

I encounter a similar issue, which I think it's the ide suspend/resume
issue. Every time if I heard the sound of the harddisk initializing, my
desktop's S3 resume works. Every time I didn't hear it, the resume
hangs. And after I reboot the system the BIOS reports a checksum error.
The symptom always can be reproduced.

>From the ACPI spec, harddisk hasn't standard method to support
suspend/resume. And it should do:
Powering down (or .suspend method)
*	Call _GTM.
*	Power down drive (calls _PS3 method and turns off power planes).
Powering up (or .resume method):
*	Power up drive (calls _PS0 method if present and turns on power
planes).
*	Call _STM passing info from _GTM (possibly modified), with ID
data from
*	each drive.
*	Initialize the channel.
*	May modify the results of _GTF.
*	For each drive:
		Call _GTF.
		Execute task file (possibly modified).

I could help write the ACPI related code for this, but I know few about
the ide controller.

Thanks,
Shaohua
