A regression..

I'm seeing the same problem in 2.6.25-rc1 on x86_64, due to something which
changed in the softlockup detector (it's a mystery and debugging is in
progress).  Setting CONFIG_DETECT_SOFTLOCKUP=n "fixes" it.

But 2.6.24 is OK.

I have set  CONFIG_DETECT_SOFTLOCKUP=n to no but it doesn't work on Sparc64.
Comment 3 Natalie Protasevich 2008-04-22 08:16:38 UTC 
Maybe Dave can give a hand on this...
Comment 4 Daniel Smolik 2008-04-25 03:46:42 UTC 
2.6.25 still don't power off

Comment 5 David S. Miller 2008-05-21 21:16:56 UTC 
Do you even see the "Power down." message on the console?

If not, something higher up is wedging, perhaps it's
the kernel_shutdown_prepare() call chain.  Most likely
it's hanging in device_shutdown() which traverses over all of the
active devices and shuts them down.
Comment 6 Daniel Smolik 2008-05-23 12:49:37 UTC 
No ,latest message which I see is System halted.
