I have recently installed 9.1 and attempted to upgrade to 10.0-CURRENT yesterday (largely in an effort to test the new radeon DRM code). Unfortunately, upon rebooting, I am left at kernel debugger prompt: cd0 at ata0 bus 0 scbus0 target 1 lun 0 cd0: <TSSTcorp CD-ROM TS-H192C DE00> Removable CD-ROM SCSI-0 device cd0: 33.300MB/s transfers (UDMA2, ATAPI 12bytes, PIO 65534bytes) cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed panic: g_read_data(): invalid length 0 cpuid = 0 KDB: enter: panic [ thread pid 13 tid 100014 ] Stopped at kdb_enter+0x3e: movq $0,kdb_why db> bt Tracing pid 13 tid 100014 td 0xfffffe0002957490 kdb_enter() at kdb_enter+0x3e/frame 0xffffff800026a960 vpanic() at vpanic+0x147/frame 0xffffff800026a9a0 kassert_panic() at kassert_panic+0x136/frame 0xffffff800026aa10 g_read_data() at g_read_data+0x45/frame 0xffffff800026aa50 g_label_ntfs_taste() at g_label_ntfs_taste+0xde/frame 0xffffff800026aa90 g_label_taste() at g_label_taste+0x37b/frame 0xffffff800026ab60 g_new_provider_event() at g_new_provider_event+0xda/frame 0xffffff800026ab80 g_run_events() at g_run_events+0x167/frame 0xffffff800026abb0 fork_exit() at fork_exit+0x84/frame 0xffffff800026abf0 fork_trampoline() at fork_trampoline+0xe/frame 0xffffff800026abf0 --- trap 0, rip = 0, rsp = 0xffffff800026acb0, rbp = 0 --- I'm no expert, but it appears to be related to the NTFS partition I have on a separate hard drive. Any ideas what the problem might be or how to debug this further? Adam
