Hi Lists,
I understand this type of ask for help may be slightly off topic here,
but hoping for some clue to my desperation, here it goes:
I am running a linux machine with a self programmed pvr running on it.
All is well until I reinstalled the linux system a few weeks ago. Now
I am suffering from random reboots. The reboots does not leave any
debug messages or clues. After some isolation, I finally narrowed it
down to a blankscene marking program -- bkmark. Running bkmark against
any recording randomly reboots the computer. By random, I mean it may
complete sucessfully once, but repeating it for a few times, the
reboots will happen. On average, it reboots every 2 - 3 runs.
I am happy with and used to seg faults, which given time, I can
debug it. But this random reboots stuff is new to me and I have no
clues at all. How and why would a user land program reboots the
system?
I am running debian stable. Self compiled unpatched kernel 2.6.16.15
PREEMPT. Single Pentium 2.8GHz on Intel 865P motherboard. bkmark uses
libmpeg2 shared library. The source code is 471 lines, availible on
request. The same program runs without problem on the system before
(debian unstable) and even before (debian stable, but that was 5 months
ago) and even with the same kernel (2.6.14.6, I updated the kernel
after this problem occured).
More info is availible but I felt it may be inapprorate to post here
and honestly I have no clue which info is relavant. Any suggestions
or clues or advices on how to debug or narrow down the cause are very
appreciated.
Thank you.
