Recently, I found that my N900 reboots unexpectedly very often. it usually happens after I finish a phone call (receiving calls seem to be ok.) I just found that the last boot reason is 32wd_to. The firmware running on my system is PR 1.3. One application that I run a lot when the crash happens is Dorian. I don't know if it has anything to do with the crash.

Anyone have any idea how I can fix this?
Thanks.

That means the watchdog reset the device. It could be many things. You may want to enable syslog to see what was happening before the reboot, and report a bug.

Well, now that overclocking can't be framed as the culprit, what's left?

I would be thinking about reflashing.

Some programs force my phone to reboot.
But not always. Kernel independent.

When I installed SPB TV made it force reboot on first run, but not since.

Here is syslog entry around the time when the phone rebooted.

Report this to https://bugs.maemo.org/show_bug.cgi?id=9150 " Device doesn't respond via UI. syslog reports HWRecoveryResetSGX: SGX Hardware Recovery triggered, sgx_misr eating all CPU"

EDIT: please vote for bug too.

And don't forget to write that you do NOT like reboots after that - they discuss an exactly this way to solve a problem (battery depletes due to hard loop).
