IDE Hard drive doesn't work after resume from S3 on Acer Aspire 1314

Bug #14494 reported by Albert Vilella on 2005-03-24
Affects Status Importance Assigned to Milestone
acpi-support (Ubuntu)

Bug Description

Suspend to RAM fails when I try to do a /etc/acpi/ in my laptop.
Shuts X correctly, normally and really fast (1
or 2 seconds), all the hardware sleeping, the power indicator LED blinking.
But, when I press the "Power" key in my keyboard, or any of the special keys, X
session restores ok,
keyboard and mouse input ok, all fine but the hda seems to have trouble
recovering (hda led blinking hard), can't execute any command because the hda is
not accessible. Kernel outputs DMA timeouts for the hdd... After half a minute,
decides it can't restore, and goes for a controlled shutdown.

Steps to reproduce: Go "suspend" to S3. It goes to sleep mode, the power LED
blinks. If I press the power or specials button, it restores graphics, keyboard
and mouse
are working but hda has problems.

This is a laptop where the HD had to be changed for another about a year ago.
The original harddrive is not there then. I wonder if this has to do with any
miscommunication issue between the BIOS (dsdt) and the hardware/kernel...

Would a reassambled dsdt help? Note that the reassemblage does not give any
error neither warning.

this happens both with DISABLE_DMA=true or commented

Seems that some people in the kernel ml complained about this:

I have also tried several combinations of "apm=off" "ide=nodma" "noapic" "nolapic"
and they also result in the hda problem _or_ in recovering to the startup bios
where a normal bootup, instead of a wakeup, is triggered... weird.

Linux currently has no real support for setting up IDE interfaces on resume.
Some machines are kind enough to set the IDE interface up themselves, but on
others we're doomed to failure. I'm looking into implementing this, but it won't
happen until some time after Hoary.

laptop mode can stop and restart the HD spinning while on batteries with no
problems - not sure if that adds any useful info

Albert Vilella (avilella) wrote :

Matthew, is anything being done kernel-wise or ubuntu-wise around this issue?
Can I provide any other info?

Matthew Garrett (mjg59) wrote :

I haven't managed to get the upstream kernel guys interested in this, which
probably means I'll need to look at writing it myself at some stage. I'm kind of
busy at the moment, so don't expect anything too quickly...

Albert Vilella (avilella) wrote :

My bug report in redhat bug tracker was already sent upstream by Alan Cox:

So I suppose that means it already is in the "to do" list in the upstream bug
tracker... (kernel?)

Matthew Garrett (mjg59) wrote :

The 2.6.12 kernel in Breezy should fix this issue (though please wait until the
version that should be out on Monday - there are currently other power
management issues with the kernel in Breezy)

Albert Vilella (avilella) wrote :

hibernate (suspend-to-disk) works fine under Breezy Col3

sleep (suspend-to-ram, i.e. S3) same problems with 2.6.12-7-k7 kernel as of Monday.
I assume this is not yet the kernel version that should work, right?

Matthew Garrett (mjg59) wrote :

Hmm. No, that one includes the code that I'd hoped would fix that issue, so it
sounds like there may be something else going on. I'll look into this further.

Same problem here with Acer TM800. Any progress on this issue?

Albert Vilella (avilella) wrote :

It wooooorks!!!

I installed official Breezy today and it works nicely!!!

Thank you Matthew and company for the great job!!!

Good to hear :)

Albert Vilella (avilella) wrote :

Well, it seems that it plays well _sometimes_:

If the time lapse between the sleep and the wake-up is prolonged, it won't wake
up properly: it simply reinitiates from the BIOS as if it where turned on or

Could this have any relation with laptop_mode?

Is there anything I can test to bring more information?
