I would try updating to a snapshot to see if it helps the axen errors/panic.
I don't think "boot dump" is possible with USB storage.

Hello again,
By way of update, if the kernel panic occurs as first described, boot
dump seems to cause the system to hang on the message 'syncing
disks...' and I have to carry out a hard reset. Not surprisingly, on
boot, savecore reports that there was no core dump.
