Laptop freezes after suspend/resume



Hi,
I am having issues with suspend/resume in my laptop (HP EliteBook 6930p). I
am running Debian Sid with 2.6.39-2-686-pae Linux kernel. After 3 or 4
suspend/resume cycles my laptop freezes during next resume. I dont see any
errors in the kernel log. Is this a known issue? How can I find more info
about what is causing this issue?

Thanks
Damu
