I saw some commits to kern so updated just to check, same results
(that's +10 EST in the dmesg below btw). I was wondering why my other
domu boots but this one fails. I realised there was an entry in the
failing domu's fstab that referenced a device/fs not currently being
exported to the domu. Removing this entry prevents the panic.
The entry was:
/dev/xbd1a /usr/local/svc/storage0 ffs rw 0 0
So it looks like it's an issue with mount_ffs identifying a non-existent
fs and moving on.
So the two problems I've encountered are xen+wapbl cause idle loop and
fstab entries for non-existent filesystems causing a panic.
I hope this info helps :) ... I'm still more than happy to poke around
for the rest of today but after that I'll be back into my usual routine
and won't be able to test anything quickly.
The dmesg/panic from 10 mins ago, just for the record:
