please attach the output from dmesg -s64000 and the output from acpidmp, found in /usr/sbin, or in pmtools here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils Created attachment 4333 [details]
Output from acpidmp
Attached as request the output from acpidmp.

Output of dmesg
As requested, output from dmesg -s 64000. However there is a problem: I'm
pretty sure this is not long enough for your needs, i.e. does not go all the
way back. I don't know how to make it longer. If you let me know, i'll do my
best.
thanks, Matt

Output from dmesg
Have recompiled my kernel with a bigger buffer size, so now here is the whole
of dmesg. Hope this helps, and that this problem can be tracked down.
I experience the same problems, first I suspected the BIOS is at fault, but a well known commercial operative system does not show the same symptoms. I am using a 2.6.11.10 kernel on a Pentium-M 745/ICH-4 Laptop (Littlebit Razor Z81). I will try to attach the different logs... Created attachment 5071 [details]

This possibly is the EC issue. Please try the latest -mm tree, which includes the burst mode EC read/write patch. I don't know about Mathew East, but at least in my case acpi info is much vivid with kernel rc4-mm2. Hope the relevant patch gets rapidly integrated into stable, such that swsusp2 patch applies cleanly again... Thanks. I still have this problem: no battery status. Recently I installed Windows to ensure this wasn't a hardware problem: works fine. I've been without battery status since 2.6.9 :/ I still have this problem with the current Ubuntu unstable kernel (2.6.12 plus Ubuntu patches). I was thinking that perhaps it would help to try an unstable kernel: could you point me to a kernel that I can try to see if this problem is solved in your latest development tree? I'm really keen to sort this problem out because being without battery status is a huge blocker for me! Matt Could you try linux-2.6.13 with patch filed at bug 3851 (id: 5574) Please try both burst_mode=0 and burst_mode=1 ok I've downloaded that kernel and have applied that patch, it's building now so I will let you know. I'm not sure how to set burst_mode=0/1 however: I can compile a kernel but I am not very knowledgeable about how it works! Matt Ok I booted that kernel but I did not have any battery status changes: I booted up with AC power enabled, then took the plug out: no change in battery status. :( M boot kernel with option: ec_burst=1 Yes, that fixes it! It also fixes my inability to change the screen brightness, which i noted in Ubuntu bugzilla here: http://bugzilla.ubuntu.com/show_bug.cgi?id=10512 Thanks for your help! Will this patch be available in the stable kernel soon? *** Bug 3516 has been marked as a duplicate of this bug. *** *** Bug 5048 has been marked as a duplicate of this bug. *** Does Linux-2.6.20 work without any cmdline parameters? Please reopen this bug if it's still present with kernel 2.6.22. |
