A "camcontrol reset 0:3:0" (trying to reset da2) reliably hangs the system (no response from the command, everything hangs). Error messages on console: (xpt0:ahc0:0:3:0): Bus Device Reset Message Sent ahc0: Bus Device Reset on A:3. 1 SCBs aborted. The hang occurs whether the system runs a uniprocessor or an SMP kernel, and it doesn't matter which disk is attempted reset either. The kernel responds to Ctrl-Alt-Esc, but the DDB backtrace doesn't seem to be very helpful: Debugger(c0244008) at Debugger+0x37 scgetc(c0277e0c,2,0,c0277e0c,0) at scgetc+0x7ec sckbdevent(c0277e0c,0,0,0,c8c82360) at sckbdevent+0x58 atkbd_intr(c0277e0c,0,0,0,c0210a8e) at atkbd_intr+0x1f atkbd_isa_intr(0,80000000,10,c0210010,0) at atkbd_isa_intr+0x28 Xresume1() at Xresume1+0x2b --- interrupt, eip = 0xc021bd71, esp = 0xc024f42c, ebp = 0 --- default_halt() at default_halt+0x1 Steinar Haug, Nethelp consulting, sthaug@nethelp.no ---------------------------------------------------------------------- Copyright (c) 1992-1999 FreeBSD Inc.
