Re: Kernel bug with btrfs on laptop with external hd and suspend and resume.

I booted up my laptop with my eSATA drives attached and mounted.  I then
closed the lid without logging in.  It then when to sleep mode.  I was
wrong in my first post about the computer suspending.  It didn't suspend
to disk, as I would have noticed the hd light.  The drives where not
unplugged at any time.  It looks like the problem occurred when trying
to stop the disks.  I was able to do a hard reboot and the disk came up
fine.  Once again I hope that this helps.
