Luk?? Hejtm?nek
Applied to ACPI tree.
Linus,
I reproduced this issue on my T61, and saw it go away w/ this patch.
I'll be sending you a pull request probably Sunday night w/ this
pach in it. But if you are in a hurry to cut rc4 before then,
consider this an Acked-by: Len Brown <[email protected]>
thanks,

I've udpated the BIOS on my T61 to 1.26 to match yours, but

If it still fails for you, please send me your .config
