Comment (by [EMAIL PROTECTED]):
I configured kernel logging adding line "kern.* /var/log/kernel" in file
/etc/syslog.conf.
After computer freezes because of this bug, it needs to be restarted. But
there was no log in /var/log/kernel abut the crash.
Yesterday, something very strange happened: I have seen the same messages
in the terminal, but the computer was not blocked.
Also, all the messages appeared in /var/log/kernel, so I am able to
provide the kernel logs:

I have not tried refcount branch. How do I get that?
I see that if computer blocks, it does not write anything in the log file.
Is the log method that I used correct?
I see this problem very frequent now, so I can provide more informations
about it if needed.
