Subject: WARNING - WRITE_MUL underrun


| Just a quick question, are these warnings harmless? Can I safely ignore
| them? This is on a fairly recent current, 1st of July. The only other
| references to this warning were from 2003, so I expect I am a minority
| here!

Someone please help me out here? :-)  Would these cause a hang... well half
a hang, I could switch terminals on the console, first console had a load
of those messages like above. Network stuff was still working by IP only, I
think... I could ping 10.0.0.1 and it would respond but pinging by hostname
wouldnt.. couldn't login to ssh, because of hard disk activity perhaps? Has
this been properly fixed in a newer current?
