Subject: Re: 2.6.23-rc6-mm1: atomic counter underflow
Hello,
I wrote a simple script that finds all modules in /lib/modules/`uname -r`
and performs sth like 'modprobe $x; rmmod $x;' for every of them. The result is the
output below. This actually happens when rmmod'ing a module.
I narrowed it down to modules mmc_core and firewire_core. To reproduce that just
rmmod them.
PS. X doesn't work but that's another story.
Regards,
Mariusz
