semi-OT: how to backtrace into the kernel when it's stuck

[dannym]

Hi,

this is kind of off-topic but ...

You know, I have this dvd drive...

when hald is running and I issue mount on the drive, mount will hang and
not let itself be killed by any means. (the mount will neither succeed
nor fail but will just be "halted")

when hald is not running, it works fine.

Now I thought it would be nice if I could debug that and for that it
would be nice to see where in the kernel it is waiting around (for some
lock, I suppose) for that mount process.

Any ideas how to debug this on the hal side would be nice too :)


cheers,
   Danny
