Weird issue with pm-suspend and libatasmart

steffinger · 2011-02-07 10:07:23

Hi everyone,

i got serious problems with suspending to disk. I run an Asus F5SL Laptop and after suspension the waking up process produces an error which looks like this in the error.log:

Feb 6 19:55:32 localhost kernel: ata1: ACPI set timing mode failed (status=0x300b)
Feb 6 19:55:32 localhost kernel: ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

Feb 6 20:03:02 localhost kernel: sr 0:0:0:0: timing out command, waited 120s

and if i then want to suspend again I get following message in the error.log:

localhost kernel: Freezing of tasks failed after 20.01 seconds (1 tasks refusing to freeze, wq_busy=0):

This means I can only suspend once everytime i boot up. I'm searching the internet and working around with this issue for more than one week now and the latest I found is: When I delete /usr/lib/libatasmart.so.4.0.3 and /usr/lib/libatasmart.so.4 i can suspend to disk as often as I want but i still get the error as the one above, just without the kernel timing out command.

I try to provide some more Information about my system:

The pm-suspend.log is not very informative as I use laptop-mode:

enabled, not active
/usr/lib/pm-utils/sleep.d/01laptop-mode resume suspend: success.

Removing libatasmart is not really an option for me because I use Gnome and libatasmart is necessary for automounting as I understand.

Does anyone have any advices? What else can I provide for you to understand the problem? Is it a bug and how to file it? Where can I read more about problems like this?

Thank you for any help.

After some time I recognized that I went into the wrong direction before. I got, that my real problem is not libatasmart, but the module sr_mod which is timing out and causing ksoftirqd to run with 100% cpu-usage of one processor thread (which is very nice, because otherwise the kernel would crash because of all the soft interrupts). So I went on and removed sr_mod temporarily.

rmmod sr_mod

This works pretty well for me since I can suspend now as much as I want and the system wakes up after all. I still get this small message:

ata1: ACPI set timing mode failed (status=0x300b)

after resume, but this seems not to be a bigger problem.

The more interesting thing is, that you can not mount CDs or DVDs if you remove sr_mod from the kernel, because that is what I think it is made for. As I still like to use this type of media, it is pretty annoying, that I can't

modprobe sr_mod

after a resume, because than I get a lot of small soft interrupts and sr_mod is timing out again.

Btw: I use a laptop with a SIS 966 chipset. Might that cause all the trouble? Can anyone think of any further reading or trying or bugreporting?
