Sorry to be such a bother about this, but I'm still having trouble. I've
read through that guide, but couldn't find anything related to nohdparm.
I found a bunch of files on my computer which included the text
hdparm, but I still have no idea what it does or how to boot without
it. Is there any chance you can explain in brief how to do this? Or
point me to someone who could? And just to be clear, I'm trying to boot
*without* *nohdparm*, correct? That double negative (without...no...) is
mixing me up. Thanks in advance if you have the time/energy to continue
helping me out with this.

The aim is for you to boot *with* the nohdparm option.  The guide
provides information about how to add extra options when booting, in
general; 'nohdparm' is the specific option you need to add to your boot
commandline.

[Bug 340014] Re: Samsung NC10 fails suspend/Resume tests

2010-05-25 Thread Alexander Johnson
Has this been fixed? I'm running a relatively fresh install of 10.04
with the latest Kernal on my NC10 (with most recent BIOS) and am still
having trouble suspending and resuming.

The only setup that works for me is when I suspend from the system menu
with my AC cord plugged in. When I select this option, the screen saver
comes on for one or two seconds and then the computer goes to sleep.
When it wakes back up, the screen saver is on for a moment and then I
get the screen unlock screen where I have to enter my password.

I've also tried without the AC cord, by pressing the Sleep key (Fn +
F1) and by closing the lid, none of which work. When I awaken the
computer (using the power button) I get only a blank screen and cannot
use any controls. I'm forced to shutdown by holding down the power key.
Interestingly, suspending using these settings (no AC cord, or by
pressing the sleep key, or by closing the lid) don't turn on the screen
saver for a split second either. It seems that when the screen saver
turns on during the suspend process, then I'll be able to wake back up.

Does anyone have any ideas where I should go from here? I'm getting the
idea that everyone else has worked out a solution to this problem.

I recently learned that upower is calling pm-powersave, *in addition* to
acpi-support calling it.  This would appear to explain the reappearance of
the problem, after it was thought to be fixed in karmic before release.

Could you try commenting out the 'pm-powersave' line in /etc/acpi/power.sh,
and see if this fixes your suspend/resume problems?

If it doesn't, you're probably experiencing a different bug.

Well, the acpi-support issue is already tracked as bug #582471, so
closing the acpi-support tasks here that I just opened.

Thilo-Alexander, can you test whether this problem is still present for
you in Lucid when booting without nohdparm, and if so, can you try
disabling /etc/acpi/power.sh as described to see if that resolves the
problem for you?

If you're using Grub2 (which is the default when installing Ubuntu 9.10 or
later), information about changing the default boot options can be found
here: https://help.ubuntu.com/community/Grub2#Configuring%20GRUB%202

 and how to disable /etc/acpi/power.sh?

If you've commented out the pm-powersave call, then it *is* disabled, as
that's the only thing the script does.

I can confirm that I see no more hdparm invocations after specifying
nohdparm. Proving that the bug now no longer appears under any
circumstances is kind of tricky for a sporadic problem, but I tried
dozens of power adapter state changes and a couple of suspend/resume
cycles and have not seen the issue surfacing again.

2009-11-08 Thread Steve Langasek
In addition to CONTROL_HD_POWERMGMT, there are two other hdparm settings
that may be set: CONTROL_HD_IDLE_TIMEOUT and CONTROL_HD_WRITECACHE, and
of these, CONTROL_HD_IDLE_TIMEOUT is also set by default.  I don't think
this problem is limited only to APM calls, but that any hdparm calls
contribute to triggering it.

You shouldn't need to patch your kernel to get a trace of apm calls,
though; a simple wrapper script should do the job:

$ sudo dpkg-divert --add --local --rename /sbin/hdparm
$ cat | sudo tee /sbin/hdparm
#!/bin/sh

echo called with args: $@  /var/log/hdparm.log
exec /sbin/hdparm.distrib $@
^D
$ sudo chmod a+x /sbin/hdparm
$

This should give you a log in /var/log/hdparm.log showing every
invocation of hdparm on the system.

I don't think you need to disable laptop-mode completely, but I think
you probably want to set CONTROL_HD_POWERMGMT=0 to let pm-utils take

Do you have laptop-mode enabled on this system, or anything else that

suspend/resume worked reliably after the changes tha have been made.

For me the bug seems to be fixed after upgrading to karmic. I tried to
suspend/resume about 15 times without any errors.

The above mentioned file /etc/pm/sleep.d/99laptop-mode doesn't exist on my 
system.
Relevant settings in /etc/laptop-mode/laptop-mode.conf:

I did those tests on battery... Steve, would you recommend to disable

2009-11-07 Thread Thilo-Alexander Ginkel
I had CONTROL_HD_POWERMGMT set to 0, so my assumption was that laptop-
mode would not issue any APM calls to my HDD. I will patch my current
kernel again so that APM calls are traced again, so I can better
quantify the calls that are made.

(BTW, sorry for the duplicate status change, my Internet connection was
kind of unstable when I did the changes.)

acpi-support has been fixed in karmic to not call hdparm -B further; the
remaining calls to hdparm (on power event and resume) are in pm-utils.

2009-10-06 Thread Steve Langasek
The changes to acpi-support are already in the archive, but are not
actually related to the resume hangs at all - I was merely saying that
pm-utils is the package that's calling hdparm on resume, so that's what
needs to be fixed.

As I mentioned on IRC, there is a fix to a /related/ bug in the archive
now for pm-utils: we were unnecessarily calling hdparm -B twice on
resume, we've now cut this down to one call.  So this should improve
resume times in general for folks, and *may* be enough to let the NC10
avoid hanging; but if not, we can cook up a quirk mechanism based on the
above DMI information.

Latest update of apci-support package from the archive +  rm

With the acpi work around I was able to suspend and resume, removing
power cord before/after suspend/resume over 30 times with no errors. I
believe this an acceptable threshold. Marking this bug as fixed for

2009-10-06 Thread Steve Langasek
Note that the relevant fixes were to the pm-utils and laptop-mode-tools
packages, not acpi-support; acpi-support had a gratuitous call to hdparm
but only in a path that was unrelated to this bug.

Fixing pm-utils and laptop-mode-tools cut the number of back-to-back
'hdparm -B' calls on resume from 3 to 1.  The power transition event
from unplugging the power while suspended would add an extra 1 call (via
gnome-power-manager+devkit-power), so this is a max 2 'hdparm -B' calls
vs. 4 before.

Since the problem was only being reported in the case where hdparm -B
was being called 4 times back-to-back, we are probably now safely below
the threshold where we'll trigger this; but a quirk blacklist *can* be
implemented, if this problem recurs.

[Bug 340014] Re: Samsung NC10 fails suspend/Resume tests

2009-09-05 Thread Thilo-Alexander Ginkel
After a lengthy analysis via the referenced Linux Kernel bug report
(thanks, Tejun!) it turned out that the HDD most commonly built into the
NC10, a SAMSUNG HM160HI, responds kind of picky when handling the APM
feature of the ATAPI SET FEATURE command (typically invoked by hdparm
-B) and most likely gets stuck if it receives the command while some
load is placed on the system or it receives the same comand multiple
times in a row.

There are two candidates, which do this after resuming and/or changing
the battery state: laptop-mode and acpi-support.

While laptop-mode offers a switch (CONTROL_HD_POWERMGMT) in /etc/laptop-
mode/laptop-mode.conf to turn off this behavior, acpi-support offers no
way of turning off this behavior (apart from turning on
CONTROL_HD_POWERMGMT for laptop-mode). If you'd like to debug which
commands are sent to the HDD, there is a debugging patch available,
which allows printing out all non-data related commands sent to the HDD:
http://bugzilla.kernel.org/show_bug.cgi?id=13416#c51

Consequently, I am switching over this report to the acpi-support
package.

As a quick workaround, get rid of all 90-hdparm.sh files below
/etc/acpi/ and make sure that CONTROL_HD_POWERMGMT is set to 0 in /etc
/laptop-mode/laptop-mode.conf.

Hi

I'm still getting this error on a regular basis - especially when I
plug or unplug the power (and the power states change).  It generally
leads to a system freeze and I loose work.

I'm currently running Jaunty with 2.6.30-020630-generic.

Is there anything I could do to prevent this error from occurring while
a fix is being developed?

2009-04-16 Thread Manoj Iyer

I had email communication with Tejun Heo, and here is the chain of thoughts: 

 I am looking at a launchpad bug  
   
 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/340014  
   
  
   
 What I am doing is:  
   
  
   
 1. suspend/resume with AC plugged in 
   
 2. suspend/resume with AC unplugged  
   
 3. suspend/resume with AC plugged in 
   
 4. suspend plugged in, remove AC power, resume   
   
 5. suspend with AC removed, plug in AC power, resume 
   
  
   
 Usually after 3 (or 4) I get:
   
  
   
 ata1: link is slow to respond, please be patient (ready=0)   
   
 ata1: SRST failed (errno=-16)
   
 ata1: soft resetting link
   
  
   
 ata1: reset failed, giving up
   
 ata1.00: disabled
   
 ata1: EH complete
   
 sd 0:0:0:0: [sda] Result: hostbyte=DID_BAD_TARGET
   
 driverbyte=DRIVER_OK,SUGGEST_OK  
   
 end_request: I/O error, dev sda, sector 152855535
   
 Aborting journal on device sda1. 
   
  
   
 After some long hours of debugging I find that when the above happens
   
 the ata taskfile status register ap-ioaddr.status_addr is set to
   
 0xd0. returned by function: ata_sff_check_status(), as a result, 
   
 ata_eh_reset() fails.
   
  
   
 Any idea what might be going on? Any pointers to help me debug/fix   
   
 this further is really appreciated.  
   

  
Looks like the device or HSM (likely the device) is locking up after
  
some disturbance at the link.  Link problem isn't too surprising after  
  
suspend/resume cycle or AC plug in/out.  libata EH can handle those 
  
event just fine.  The problem here seems to be...   
  

  
* The device needs hardreset to get back to operational state again.
  

  
* Unfortunately, ICH7 currently can't access sata control registers in  
  
  ata_piix mode, so it can only do softreset.  From ICH8 on, hardreset  
  
  works because SCRs are accessible via SIDPR.

Ok, after some further testing I set the SATA mode on my NC10 to
Enhanced using the hidden BIOS menu described above. The error seems
to be gone, i.e., I have neither been able to reproduce it during
suspend/resume or boot nor using the instructions from

Sounds like a BIOS bug that probably needs to be worked around...

The BIOS does have some hidden settings, one of which enables setting
the SATA mode. The problem is that the default (at least in BIOS version
04CA) already is Compatible. To show the undocumented settings, enter
the CMOS setup (by hitting F2 during boot). Then, press Fn+F11 followed
by Fn+F12. Use a cursor key to force a screen redraw. An Intel menu
entry will appear. The SATA settings are located at Intel - ICH

I am seeing these errors on resume when there is a transition of power
state from AC unplugged to AC plugged in or vice versa.
ata_check_ready() reads the status register which contains the value
0xd0 when the ATA reset error occurs, 0xd0 is not a valid value, and
SRST fails and eventually the error handling routine give up trying to
reset the device. There are some upstream patches to libata but those
dont fix this problem.

Similar problems have been reported on other Laptops and the suggestion
that worked frequently is to change the BIOS setting for SATA from
extendend mode to compatible mode. But the current bios version does not
provide any options to change SATA settings.
