------- 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): commit 1b7fc5aae8867046f8d3d45808309d5b7f2e036a Author: Alexey Starikovskiy <[EMAIL PROTECTED]> Date: Fri Jun 6 11:49:33 2008 -0400 ACPI: EC: Use msleep instead of udelay while waiting for event. http://bugzilla.kernel.org/show_bug.cgi?id=10724 Signed-off-by: Alexey Starikovskiy <[EMAIL PROTECTED]> Signed-off-by: Len Brown <[EMAIL PROTECTED]> -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
