Just updated my CURRENT partitions on my testbed and laptop. The laptop just boots but I've managed to capture this on my testbed (attached to a serial port on another system). This is HEAD from yesterday (Apr 15) morning (PDT). The partition being booted is ada0s1d. On my laptop it's ada0s3a. KSTACK_PAGES is 4. Is there a way to quickly display that kern.kstack_pages from DDB? ada0 at ata0 bus 0 scbus0 target 0 lun 0 ada0: ATA-7 device ada0: 100.000MB/s transfers (UDMA5, PIO 8192bytes) ada0: 76351MB (156368016 512 byte sectors: 16H 63S/T 16383C) ada0: Previously was known as ad0 ada1 at ata0 bus 0 scbus0 target 1 lun 0 ada1: ATA-7 device ada1: 133.000MB/s transfers (UDMA6, PIO 8192bytes) ada1: 117246MB (240121728 512 byte sectors: 16H 63S/T 16383C) ada1: Previously was known as ad1 ada2 at ata2 bus 0 scbus2 target 0 lun 0 ada2: ATA-8 SATA 2.x device ada2: 300.000MB/s transfers (SATA 2.x, UDMA5, PIO 8192bytes) ada2: 476940MB (976773168 512 byte sectors: 16H 63S/T 16383C) ada2: Previously was known as ad4 ada3 at ata3 bus 0 scbus3 target 0 lun 0 ada3: ATA-7 SATA 2.x device ada3: 300.000MB/s transfers (SATA 2.x, UDMA5, PIO 8192bytes) ada3: 305245MB (625142448 512 byte sectors: 16H 63S/T 16383C) ada3: Previously was known as ad6 SMP: AP CPU #1 Launched! panic: stack overflow detected; backtrace may be corrupted cpuid = 1 KDB: enter: panic [ thread pid 13 tid 100009 ] Stopped at kdb_enter+0x3d: movl $0,kdb_why db> bt Tracing pid 13 tid 100009 td 0x872d6000 kdb_enter(80ca7886,80ca7886,80ca9523,86edcae0,1,...) at kdb_enter+0x3d/frame 0x86edca98 panic(80ca9523,86edcb70,80713dd2,86edcbd8,86edcafc,...) at panic+0x141/frame 0x86edcad4 __stack_chk_init(86edcbd8,86edcafc,86edcaf8,86edcafc,64,...) at __stack_chk_init/frame 0x86edcae0 g_label_disk_ident_taste(87b7dc80,86edcbd8,80,0,0,...) at g_label_disk_ident_taste+0x102/frame 0x86edcb70 g_label_taste(80d26b88,872ff500,0,872ff480,872d6000,...) at g_label_taste+0x3ca/frame 0x86edcc6c g_new_provider_event(872ff500,0,25c,80c9798e,0,...) at g_new_provider_event+0xb1/frame 0x86edcc88 g_run_events(0,86edcd08,222db60d,83725616,b10094f2,...) at g_run_events+0x19f/frame 0x86edccc4 fork_exit(8070d140,0,86edcd08) at fork_exit+0xa3/frame 0x86edccf4 fork_trampoline() at fork_trampoline+0x8/frame 0x86edccf4 --- trap 0, eip = 0, esp = 0x86edcd40, ebp = 0 --- db> I've been poking at this off and on last night.
