dmesg

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.2.0) Gecko/20100115 SUSE/3.6.0-145.1 Firefox/3.6

On my Lenovo S10 suspend to disk and suspend to ram work great.
Except for one thing. After every 10th to 20th suspend to disk the system becomes horrible slow.
Such a suspend takes 30+min to write all pages to disk.
Resuming takes also forever and after resume my system is unusable.
E.g: It takes 5min to login on tty.
After a reboot everything works great again.

Attached is dmesg's and ps fax's output.
I've canceled a slow suspend and saved both files. This took me more than 15 minutes.
The system had a uptime of 7 days and i suspended it more than 10 times.

Reproducible: Sometimes

Steps to Reproduce:
1. Call Suspend to disk
2. Resume
3. Repeat steps 1,2 10 to 30 times. :-)

You missed to attach dmesg.

However, if there will not be something very obvious in the log file, I doubt we will be able to fix this. This seems to be a problem specific to your system.

I don't think so:

What else could it be? A BIOS bug?

Btw: Today the problem happened also after resuming from suspend to ram.
Comment 5 Holger Macht 2010-06-28 08:38:31 UTC
Did you already try openSUSE 11.3? I'm just asking because I really doubt we will find the time to look into this issue further for 11.2, I'm sorry.
Comment 6 Richard Weinberger 2010-06-28 08:58:59 UTC
I'm using 2.6.34-desktop (from Kernel:HEAD) since a week on my 11.2.
The problem did not occur so far. :-)
Next week I'll give 11.3 a try.
Comment 7 Holger Macht 2010-07-28 08:02:31 UTC
Closing for now. Please reopen if the bug persists for 11.3, thanks.
