------- Comment #6 from [EMAIL PROTECTED]  2008-10-24 01:01 -------
There were no such problems with kernels <= 2.6.25.x. At least I don't remember
them. I own this laptop since times of 2.6.23-rc, so I think that 2.6.23-2.6.25
are good.

As I said, issue is difficult to reproduce, since it happens sometimemes
(rarely enough). 2.6.27 release works usually too. For example I can do 5, 10
or even 20 hibernate -> resume cycles without such problems. It just happens
sometimes.

Alexey suggested to replace msleep(1) with udelay(50) in drivers/acpi/ec.c
(there is only one place to change). I've done it. And now I got ~15-18
successful hibernate->resume cycles without any problems.

msleep(1) was introduced by followed commit (according to git annotate):

    ACPI: EC: Use msleep instead of udelay while waiting for event.
