Hi,
following up to http://mail-index.netbsd.org/current-users/2007/12/17/0002.html:
looks like I get "ahd0: failed to create DMA map for ..." now every
night. As "atrun" is running (see output of ps /l below), I suspect
this problem is triggered by /etc/nightly.
With an older kernel (from Dec. 7.) the machine is running w/o
problems.
Is there anything I can do to help tracking this down? Should I
send-pr? Relevant output from db> provided below (lines marked
"***" inserted by me)...
