1st panic: (i.p. = 0xf010553d)

Ok, but onæy because it's you ;-)
panic-on-demand (with DDB):
[doing start/stop stuff]:
panic: biodone: buffer not busy
- trace:
_biodone at _biodone+0x24
_dadone at _dadone+0x23d
_camisr at _damisr+0x1fb
_swi_cambio at _swi_cambio+0xd
doreti_swi() at doreti_swi+0xf
(machine still in DDB -- anything more precise ? I don't have a serial
cross cable right now).
