The usual behaviour of the burner is to still write on that cd-r, even after burncd exited (Usually burncd exists with I/O-error...). I waited until it finnished the write. I could not eject the media, though. Then, to test the thing, I happened to use mount instead of mount_cd9660: mount /dev/acd0c /cdrom --> panic: IdlePTD 3739648 initial pcb at 306700 panicstr: vm_fault: fault on nofault entry, addr: c47a9000 panic messages: --- panic: vm_fault: fault on nofault entry, addr: c47a9000 syncing disks... 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 giving up on 32 buffers Uptime: 8h21m28s dumping to dev #ad/17, offset 761856 dump ata1: resetting devices .. done 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 --- #0 0xc01710cc in boot () #0 0xc01710cc in boot () (kgdb) where #0 0xc01710cc in boot () #1 0xc0171469 in panic () #2 0xc023d168 in vm_fault () #3 0xc0278e92 in trap_pfault () #4 0xc0278a73 in trap () #5 0xc0250c8a in atapi_read () #6 0xc02507bf in atapi_interrupt () #7 0xc024beae in ata_intr () #8 0x8055421 in ??
