It would help if we could see the result of the sysrq-t output when the
kernel is frozen.

- enable and configure a serial console or netconsole
  (Documentation/networking/netconsole.txt)

- boot with log_buf_len=1M

- run `dmesg -n 7'

- freeze the kernel

- hit sysrq-t

- send us the resulting output.  Please don't let it get wordwrapped
  by your email client!

 Hoi,

 The SysRq-t output was already in my original bug report.  For your 
convenience, I've extracted just the SysRq-T part in the attached log.  The 
output was intermingled with some page allocation failures, but these I've 
removed again.  I've left in a few page allocation failures, hung tasks and a 
SysRq-l for good measure.

 I'm now trying to reproduce it with fewer processes and loaded modules.

 Regards,
 Arnout

Hi,

We now succeeded in reproducing the freeze with a minimal set of running
tasks and modules:
- gettys
- ssh
- fillmem.py python script to fill memory (respawned by init when killed by
oom-killer)
- wget: to introduce network traffic (respawned by init when killed by
oom-killer)
- syslog

The freeze was introduced some time after we loaded the md-crypt and mptsas
modules (without mounting any drives). Before we loaded these modules the
system was running with the same set of processes for several hours and did
not freeze. Some modules like xfs, ipmi, ext2, ext3 were compiled in kernel
and not as module.

putty_before_freeze: huge logging before we noticed the freeze
putty_task_trace_frozen: State information in frozen state
putty_blocked_trace: blocked task list, backtrace of CPUs and memory info in
frozen state

We were not able to kill any tasks with SysRq-kIll.

Kind regards,
Peter Trekels
QuESD nv.

 Hoi,

 The SysRq-t output was already in my original bug report.  For your
convenience, I've extracted just the SysRq-T part in the attached log.  The
output was intermingled with some page allocation failures, but these I've
removed again.  I've left in a few page allocation failures, hung tasks and
a SysRq-l for good measure.

 I'm now trying to reproduce it with fewer processes and loaded modules.

 Regards,
 Arnout

Hi,

We now succeeded in reproducing the freeze with a minimal set of running
tasks and modules:
- gettys
- ssh
- fillmem.py python script to fill memory (respawned by init when killed by
oom-killer)
- wget: to introduce network traffic (respawned by init when killed by
oom-killer)
- syslog

The freeze was introduced some time after we loaded the md-crypt and mptsas
modules (without mounting any drives). Before we loaded these modules the
system was running with the same set of processes for several hours and did
not freeze. Some modules like xfs, ipmi, ext2, ext3 were compiled in kernel
and not as module.

putty_before_freeze: huge logging before we noticed the freeze
putty_task_trace_frozen: State information in frozen state
putty_blocked_trace: blocked task list, backtrace of CPUs and memory info in
frozen state

We were not able to kill any tasks with SysRq-kIll.

Kind regards,
Peter Trekels
QuESD nv.

 Hoi,

 The SysRq-t output was already in my original bug report.  For your
convenience, I've extracted just the SysRq-T part in the attached log.  The
output was intermingled with some page allocation failures, but these I've
removed again.  I've left in a few page allocation failures, hung tasks and
a SysRq-l for good measure.

 I'm now trying to reproduce it with fewer processes and loaded modules.

 Regards,
 Arnout
