SUMMARY: Trap 3e on A1000, failing RAID Manager

From: Luke Kanies (

Although multiple people emailed me saying they were having basically
the same problem I am, although not usually with an A1000, no one seems
to have found a solution. I refer to bug 4166678 below, and it looks
like that bug still hasn't been fixed. So, I don't recommend trying to
boot off of an A1000, because apparently it will give the Trap 3e on PCI
cards right now.

I still have not figured out why I cannot fsck volumes, either.
