Well, I upgraded my box to current, and I have been playing around with a hard disk in a firewire enclosure... I have gotten a couple different panics... This seems to be a race between opening da0 and various operations... To stimulate these crashes, I have simply been running newfs on /dev/da0a... The latest: da0: 239372MB (490234752 512 byte sectors: 255H 63S/T 30515C) panic: Provider da0 lacks sectorsize Earlier: Fatal trap 18: integer divide fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x8:0xc07d682f stack pointer = 0x10:0xd5d976f8 frame pointer = 0x10:0xd5d97780 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 = 572 (newfs) [thread pid 572 tid 100084 ] Stopped at __qdivrem+0x3b: divl %ecx,%eax db> tr Tracing pid 572 tid 100084 td 0xc1b55450 __qdivrem(1,0,0,0,0) at __qdivrem+0x3b __udivdi3(1,0,0,0) at __udivdi3+0x16 cam_calc_geometry(d5d97834,1,d5d97da0,c0625b57,c1947084) at cam_calc_geometry+0x26 sbp_action1(c18417c0,d5d97834) at sbp_action1+0x437 sbp_action(c18417c0,d5d97834) at sbp_action+0xe xpt_action(d5d97834,d5d97834,c1a7c4f0,1,1) at xpt_action+0x28a dasetgeom(c1a22a80,ec520000,0,0) at dasetgeom+0x69 dagetcapacity(c1a22a80,8,c082c5a7,63,c1c7e180) at dagetcapacity+0x266 daopen(c1c7e180,0,0,c1a3e300,c1ab6800) at daopen+0x71 g_disk_access(c1a3e300,1,1,1,c08f8158) at g_disk_access+0xd7 g_access(c1ab6800,1,1,1,c1ab6800) at g_access+0x191 g_slice_access(c1a3e800,1,1,1,c1c97900) at g_slice_access+0x149 g_access(c1ab6900,1,1,0,1) at g_access+0x191 g_dev_open(c1c97900,3,2000,c1b55450,c1c97900) at g_dev_open+0xb6 devfs_open(d5d97a74) at devfs_open+0x183 VOP_OPEN_APV(c088de20,d5d97a74) at VOP_OPEN_APV+0x7e vn_open_cred(d5d97bdc,d5d97cdc,920,c1c7eb80,4) at vn_open_cred+0x402 vn_open(d5d97bdc,d5d97cdc,920,4,c067212a) at vn_open+0x1e kern_open(c1b55450,bfbfedeb,0,3,bfbfeb30) at kern_open+0xb6 open(c1b55450,d5d97d14,3,1,292) at open+0x1a Clues anyone? -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Sun Mar 20 2005 - 16:53:44 UTC
