Thinkpad x60 doesn't recover from suspend or hibernate

Can you try booting with the

acpi_sleep=s3_bios

argument and see if you get any output on resume?

That and "pci=routeirq" seems to be almost it.

Everything seems to come back up, but I get errors from sdhci similar to #44959.

That is, everything is the same, though my messages stop right at "Unexpected auto CMD12 error".

X seems to be up and the virtual consoles, but everything that tries to access the disk seems to hang forever. For instance, I can type a username at a console login prompt, but it hangs instead of giving a password prompt. Similar for the GDM login.

What happens if you don't use "pci=routeirq"? Thanks for the test, it sounds like the hard drive isn't being resumed correctly. Any chance you can provide the output of lspci?

If I don't use pci=routeirq, I don't get as far. It looks like the system resumes part way, but nothing is displayed.

I tried following #44959's suggestion of unloading sdhci before suspend and I got the following:
hda_intel: azx_get_response timeout, switching to single_cmd mode.

According to a google search, the problem appears to be the snd_hda_intel module.

Actually, it does appear that if I leave out pci=routeirq and then remove the snd_hda_intel and sdhci/mmc_core modules, suspend gets to the same point.

In any case, unloading snd_hda_intel doesn't appear to get me the rest of the way.

Ahh... changelog for linux-image-2.6.17 has the following:

  * Disable CONFIG_SCSI_SATA_ACPI until it's forward ported.

And, the above comment was made in May.

In June, the patch was forward-ported:

http://cvs.fedora.redhat.com/viewcvs/rpms/kernel/FC-5/linux-2.6-console-suspend.patch?rev=1.1&view=markup

Would it be possible to get that patch added?

Ok, that should be integrated. Ben's looking at that now.
