Subject: Re: on exit xterm  totally wrecks linux 2.4.11 to 2.4.14-pre6 (unkillable processes)

Message-ID: <3BE23A33.7080001@pacbell.net> (raw)

Hi,

I see something similar with vanilla 2.4.13 (+devfs), except my 
unkillable xterms don't appear until a modprobe has already failed. 
Specifically, what seems to happen is:

- an open() call causes the kernel to grab the devfs rwsem for reading, 
and then load a module (e.g. ide-cd).
- the modprobe process then waits forever for write-access to the devfs 
rwsem.

Each xterm then waits forever in "wait_for_devfsd_finished()", 
presumably when it tries to close its terminal.

Are you also using dynamic module loading? Are ALL of your unkillable 
processes xterms, or do you also have a failed modprobe lurking somewhere?

Chris
