Created attachment 11527 [details] DSDT from machine iasl doesn't report anything weird with this when recompiling, so assuming this is a kernel bug rather than buggy BIOS.
Comment 3 Nicolo' Chieffo 2007-05-17 10:54:44 UTC
also because battery is detected in kernel 2.6.20
Comment 4 Thomas Schwarzgruber 2007-05-21 06:49:30 UTC
Hello ! I'm the submitter of Bug: http://bugzilla.kernel.org/show_bug.cgi?id=8477 which seems to be very similar. Could you perhaps check if it's the same bug ? I also remember that in earlier Kernel versions I had to patch the kernel because of a broken dsdt on my machine (I use an Asus M6N). Later on this patch wasn't necessary, and I seem to have deleted it. Perhaps there was a change from 2.6.20 to 2.6.21 in that respect.
Comment 5 Nicolo' Chieffo 2007-05-21 07:18:45 UTC
yes, it is the same bug. the problem is definitely not the one you are telling, because I have a bios which fixes that problem
Comment 6 Thomas Schwarzgruber 2007-05-21 07:24:20 UTC
Great ! Than I have not to worry finding that patch again ...
Comment 7 Nicolo' Chieffo 2007-06-01 03:41:16 UTC
this also happen in fedora 7 with kernel 2.6.21!

> [\_SB_.PCI0.SBRG.EC0_.BATS] Curious, \_SB_.BAT0._STA accesses BATS through and Alias: Alias (\_SB.PCI0.SBRG.EC0.BATS, BATS) I wonder why the error message is printed EC0_ instead of EC0 Please attach the complete un-processed output from acpidump

I'm the actual submitter don't worry

Please try the patch in comment#9 bug8598.
Comment 12 Nicolo' Chieffo 2007-06-26 08:45:06 UTC
Will this patch be included if it works?

Comment 14 Borislav Petkov 2007-06-30 06:32:51 UTC
I can confirm that I had the same regression with my machine, ASUS M6B00N, and after applying the patch, the battery shows normal again. I think it would be ok to pass it for inclusion in 2.6.23 if it's not too late yet.
Comment 15 Borislav Petkov 2007-06-30 11:42:50 UTC
i meant 2.6.22 of course.
Comment 16 Nicolo' Chieffo 2007-07-11 04:16:00 UTC
I've also tried this patch and it works. You can include it in the main kernel tree!
Comment 17 Thomas Schwarzgruber 2007-07-11 04:29:08 UTC
Yes it also works for me and the patch still applies to 2.6.22 - it would be nice if someone could push it for mainline inclusion.... I'm scared by the imagination of applying this patch to every new kernel version...
Comment 18 Nicolo' Chieffo 2007-07-11 06:56:54 UTC
I've noticed that the system is quite slow (comparing to 2.6.20) to notice that the AC cable is unplugged... 5 seconds! is it normal?
Comment 19 Fu Michael 2007-10-10 01:03:27 UTC
dup of bug# 8598. it's code fixed. the slow AC unplug dection isue, please open another bug. thanks. *** This bug has been marked as a duplicate of bug 8598 ***
