Re: System Sometimes Hangs @ "Power Off" While Halting

I currently only use laptop-mode-tools for hard drive spindown. Since that's the only module I use laptop-mode-tools for, I suspect that's the culprit.

I've come to the conclusion that hard drive spindown is worthless (Linux is constantly writing logs) so I was already planning on getting rid of this. I will test this evening and report back.

I tried laptop mode tools mailing list:

As for now Ritesh Raj Sarraf answered it's not laptop mode tools related issue.

Could've fooled me. Mine is rebooting great now that I disabled it.

Kernel bug or not, as a programmer he should be able to work around it. Just my opinion though.

Did you report it upstream? aka bugtracker

I hope so, but probably not. If there's finger pointing (the developer is blaming the kernel) then it will probably be a while. Hopefully I'm wrong.

Or.. we can try to find a temporary fix or workaround for this problem.

while I think that finger pointing is lame, I believe that the developer is right when he says that it's a kernel bug, since I was able to reproduce the issue while changing the CPU governor to on-demand. A kernel developer also identified the problem here: https://lkml.org/lkml/2011/4/4/121

it would be nice if this problem gets solved with new kernels.

I'm not saying that it's not a kernel problem. It probably is. But as a developer, that's no reason to not make it work regardless. There are always if statements and work-arounds and ways to make your software work on various platforms regardless of problems on that platform/kernel.

Re: System Sometimes Hangs @ "Power Off" While Halting

I have the same problems with my Thinkpad T60p.
Only for me the problem only occures when I have wicd started. If I kill wicd before shutdown everything works fine.

Re: System Sometimes Hangs @ "Power Off" While Halting

I've got the same problem on my T410.  I suppose in some way my problem is "better" in the sense that it hangs every time, always with the "Disabling IRQ #19."

At least for me it is not a wicd or laptop-mode-tools problem, as it happened with both of these daemons stopped.  It seems that due to the nature of the problem and where it is occurring in the halt process there doesn't seem to be a way to find what is going on in the log files.

If there's any way I can supply information to help though, I would like to.

Thanks,
Ryan

Same laptop, same problem. Disabling laptop-mode works as a workaround.

I have a thinkpad W510 and disabling laptop-mode and acpid also fixed it for me.

Re: System Sometimes Hangs @ "Power Off" While Halting

I've tried to install Ubuntu 11.04 and my laptop shutdowns and reboots with no problem. FYI the kernel version is 2.6.38-8. I know they have some patches applied, I wonder if this issue is noticed by Ubuntu developers and they have a fix on that. Arch+Gnome3 would be a wonderful setup on my laptop when this shutdown issue is fixed.
