Hi,
I've built RELENG_7 from sources csupped at around 0700 UTC today.
'make installkernel', reboot, panic:
====Trying to mount root from zfs:zgm0/root

====
My ZFS pool is from well before the recent ZFS MFC. The full text of
the boot-up is below, along with loader.conf.
As maybe something of a side note, I rebuilt the kernel with
options DDB
options KDB
options KDB_UNATTENDED
options BREAK_TO_DEBUGGER
added to GENERIC, but I'm unable to access the debugger fully. Using
vidconsole, a USB keyboard is non-responsive once the panic occurs,
and this system has no PS/2 ports. I tried using comconsole, but this
system appears to have squirrely serial as well, so while I can "press
a key" and get a ddb prompt, what I type does not show up or shows up
as something else, as though there's a baud-rate mismatch.
(comconsole works fine from the loader to the ddb prompt, but it fails
to be useful once that point is reached.) Does anyone have any
suggestions as to how I can access the debugger?
Thank you for any help with any of this.
Jeff
