disk doesn't work after waking laptop from suspend

https://bbs.archlinux.org – Hi,I have a strange problem with pm-suspend. Laptop suspends and wakes up without any errors in logs and all programs that where turned on before suspend are restored nicely, and kind of works (mouse and keyboard works as well). But every time sth needs to access hard disk I get input/output errors or other strange errors. It would seem that hard disk becomes unavailable after waking up. Only way to get system working again is to force restart by pressing power button for 5 seconds. I don't really know what to do because there are no errors in logs and I can't start any program after (HowTos)
