Comment 1 Pedro C 2005-03-13 16:43:13 UTC

This seams to be fixed in 2.6.11

Comment 2 Pedro C 2005-03-13 17:36:35 UTC

This still happens in 2.6.11 after all. It may have something to do with the
ipw2100 driver.

Comment 3 Shaohua 2005-03-14 23:31:18 UTC

I got a similar issue: syslogd can't be stopped. My investigation is syslogd 
is waiting for kjournald to flush some work, but kjournald is stopped, so 
syslogd can't be stopped. The refrigerator mechanism can't handle process 
relationship.

Please close this bug if the problem doesn't occur for recent kernels (2.6.18
and later).

Comment 5 Pedro C 2006-09-28 17:18:31 UTC

I have no idea if this still applies. I don't think my current distro runs
mdnsresponder and I haven't seem similar bugs since. It should probably be
closed if no one can reproduce it.
