Tested scenarios: a) softupdates enabled, using /dev/cd1 (atapicam) Writing files to mounted filesystem causes panic: panic: initiate_write_inodeblock_ufs2: already_started b) softupdates disabled, using /dev/cd1 (atapicam) No panic occurs, writing to media works as expected. c) softupdates enabled, using /dev/acd1 No panic occurs, writing to media works as expected. This problem is probably related to kern/91568, cause in both cases problem occurs only when softupdates are enabled. Also worth mentioning: during writing to /dev/cd1 (atapicam) there is a bunch of messages on the console: Jan 9 20:02:12 data kernel: g_vfs_done():cd1[WRITE(offset=3691495424, length=131072)]error = 5 Jan 9 20:02:12 data kernel: g_vfs_done():cd1[WRITE(offset=3690577920, length=131072)]error = 5 Jan 9 20:02:31 data kernel: (cd1:ata1:0:0:0): WRITE(10).
