| |
Hello.
I use a Thinkpad t43p as my laptop, and encountered an annoying problem with suspend to ram following a hibernate cycle. In a few words, to resume after a suspend I have to manually press the power button -- resuming when opening the lid does not work.
The problem manifests only after I put the machine through a successful hibernate cycle; if I start from a fresh boot and suspend the machine by closing the lid, it comes back to life when I once again open the lid. Repeating this suspend to ram cycle using lid acpi events works flawlessly (that is, until I hibernate...)
I am currently using kernel 2.6.25 (with Gentoo patches), and have had the problem ever since I managed to get suspend to disk working. One issue which might be related is that I boot my kernel with "acpi_serialize", as otherwise I get many acpi error messages.
My suspend script is simple, something along the lines of : echo disk > /sys/power/state
I'd really like to solve this issue, and am willing to invest time towards this. However, I have no idea where to begin. I'd appreciate any pointers / advice.
Thanks.
