FATAL: Error inserting hotkey
(/lib/modules/2.6.13-rc7/kernel/drivers/acpi/hotkey.ko): No such device

Not that I care, but it at least loaded in -rc6 and created the
/proc/acpi/hotkey directory with its content.

When the revolution comes, the author of acpi-hotkey.txt will face the

If it was clearly marked as "This is INFO, not a Warning". Most users
I've met (myself included) are always expecting their hardware to crash and
burn at the drop of a hat. Scary messages just confirm our anguish - 
especially when it's coming by way of the CD/HD system.

My jaw just clonked on the table. And the media error at hand made you
buy a new CD-RW. There is precedence for this (remember the blaming X and
other programs in the keyboard driver?) so perhaps the kernel people could
amend the error like:

hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdc: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xec

Doing a "hdparm -I /dev/hdc" (without a disk/with a ISO disk/[u]mounted/music

"hdparm -i /dev/hdc" does not interfere (hdparm v6.1) and normal access like

You've probably already seen that /proc/acpi/processor/CPU1/power lists
C1 only here. Ok, with your input regarding normal CPUs I'm inclined
to believe ACPI is correct in my case. Still, I'll learn/read the code.
Always have had a need to finish those long marches.

The issue has made me fume enough to contemplating installing windos for
the first time in some 10 years. But I'll persevere. Will learn
ACPI-speak, read bios- and kernelcode. Then return, have no fear (even
if just to admit that the BIOS is buggy). Speaking of bugs, I was

C2/C3 for many systems:

Indeed. It's supposed to be some kind of neutral non-discrimatory

Because of the CPU, ACPI implementation or because of kernel acpi
quality, x86_64 kernel quirks or...? It seems crazy that a modern CPU
like this should be so backwards as to not implement sleep states. It
being in a notebook and all. I blame intel kernel hackers ;-)

I've been reading/checking up on this the last four hours since I
had a nagging suspicion that the CPU indeed didn't enter a sleep
state. With all the abbreviations in the ACPI field (S1, C1, P1 etc)
it killed a fair amount of brain cells, but I'd still call faul on this:

from /var/log/kernel
[powernow-k8 module loads processor module which says]
ACPI: CPU0 (power states: C1[C1])

and catting /proc/acpi/processor/CPU0/power gives
active state: C1
max_cstate: C8
bus master activity: 
states:
   *C1: type[C1] promotion[--] demotion[--] latency[000] usage[02998796]

/sys/module/processor/parameters/max_cstate says 8
/sys/module/processor/parameters/bm_history says 4294967295

So I'm a bit baffled that no C2/C3 turns up. I've done a test-compile
with all of ACPI in kernel instead of as modules, but there was no
difference.

I'll unload the whole USB-module part and boot without loading them, but
will it matter? Please provide more details about how to debug this
(very confusing) field.

I first thought about loading with a loop of md5sum /somedir, play a
wav, fetch a couple of webpages etc. But since the talk has been that
the powersave would come from CPU sleep between "ticks" (I know, I know,
it's not ticks) not having to wake up so often, I decided against a
load.

I won't do that unless heavily beaten ;-) The battery charge time is
2h10 minutes...

Prior to that I was running 2.6.11-rc4 from Feb 13 to Feb 24 and -rc5
from Feb 24 to Mar 3 without these freezes. But perhaps that was too
short periods to catch anything.

Adding Bartlomiej Zolnierkiewicz to the CC list since it should be in
his corner.

2.6.11 hda: dma_timer_expiry: dma status == 0x61

2005-03-03 Thread Voluspa

Out of the blue came a screen freeze. Opera browser froze, window
manager froze (not X or mouse) but gkrellm system monitor was alive and
showing no irregular activity. The freeze lasted less than a minute.
It resembled nothing I've ever seen before. Kernel log has the following
entry:

Mar  3 18:03:01 loke kernel: hda: dma_timer_expiry: dma status == 0x61
Mar  3 18:03:11 loke kernel: hda: DMA timeout error
Mar  3 18:03:11 loke kernel: hda: dma timeout error: status=0x58 
{ DriveReady SeekComplete DataRequest }
Mar  3 18:03:11 loke kernel:
Mar  3 18:03:11 loke kernel: ide: failed opcode was: unknown

My drives have thir SMART regularly checked by
smartmontools(.sourceforge.net) and doing a manual run right after this
freeze showed everything to be OK.
