After some poking around, I discovered that I can kill it reliably by running "ls -lR /". The kernel was built after cvsuping today. A kernel a week older does not have the problem. My hand transcription of the first half of the console messages are shown below (sorry, I got writers cramp - if more is needed I'll try again), along with my dmesg and kernel config file. ahc0:A:1 ahc_intr - referenced scb not valid during seqint 0x71 scb(70) ahc0: WARNING no command for scb 70 (cmdcmplt) QOUTPOS = 64 Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc013a730 stack pointer = 0x10:0xc7dd6cfc frame pointer = 0x10:0xc7dd6d0c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 5 (syncer) interrupt mask = bio cam kernel i type 12 trap, code = 0 Stopped at ahc_match_scb+0x18: movl 0(%esi),%eax db> trace ahc_match_scb(c0a28800,0,1,41,0,ff,0) at ahc_match_scb+0x18 ahc_search_quinfifo(c0a28800,1,41,0,ff) at ahc_search_quinfifo+0xf7 ahc_freeze_devq(c0a28800,c0a2e5e4) at ahc_freeze_devq+0x5d ahc_handle_seqint(c0a28800,71) at ahc_handle_seqint+0x135 ahc_freebsd_intr(c0a28800,6c0400,c0313b80,ce008000,c7dd6e5c) at ahc_freebsd_intr+0x97 Copyright (c) 1992-2000 The FreeBSD Project.
