Subject: [9fans] Bizarre freeze
Date: Wed,  6 Aug 2008 02:01:17 +0800	[thread overview]
Message-ID: <140e7ec30808051101n5df6bcdbx4ab515e643f5d9f@mail.gmail.com> (raw)

 Ran into an interesting one setting up my cpu server. The following
reliably freezes the box:

# echo dma on >/dev/sdC0/ctl
# 9fat:

 Leaves the console totally unresponsive, no ^T^Tp, no ^P. rc -x on
9fat: gives "rfork e" as the final command.
 sdC0 is a cdrom. I can turn dma on for my sata disks (sdE0/sdF0) no problem.
