It did not print out the ata3: resetting devices .. message, but it died with a panic: panic: trap: memory address not aligned Debugger("panic") Stopped at Debugger+0x1c: ta %xc, 1 db> trace panic() at panic+0xf0 trap() at trap+0x394 -- memory address not aligned sfar=3D0xdedeadc0ee sfsr=3D0x40029= %o7=3D0xc007ec28 -- ata_prtdev() at ata_prtdev+0x14 ata_timeout() at ata_timeout+0x130 softclock() at softclock+0x1a0 ithread_loop() at ithread_loop+0x1b8 fork_exit() at fork_exit+0x84 fork_trampoline() at fork_trampoline+0x8 I know nothing about lower-level sparc64 debugging, so I am probably stuck at this point. It will not be much of a problem if I have to reinstall this system, so don't worry too much about this situation until I get back to some kind of bootable system. Thanks for the suggestion though. it would have been nice if it had worked! -- Garance Alistair Drosehn =3D gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
