Error description
The kernel trace hook 0x3B9 which is used to format trace events from the Fibre Channel device driver does not format the data correctly. It attempts to use the generic 0xDD1 trace hook.
Local fix
In /etc/trcfmt locate the hook 0x3B9. It will appear as follows: 3B9 1.0 "FCDD" \ $DD1 Replace it with the following: 3B9 1.0 "FCDD" \ $HDU, \ 0xc3 { "command_out: ap: " $D3 " ctl_elem: " $D1 " iocb: " $D2 " ring: " $D4 }, \ 0xc4 { "command_in: ap: " $D3 " ctl_elem: " $D1 " iocb: " $D2 " ring: " $D4 }, \ 0x15 { "entry_intr: ap: " $D1 }, \ 0x16 { "exit_intr: ap: " $D2 " har: " $D1 }, \ 0xbf { "entry_offl: ap: " $D1 " poll_state: " $D2 " io_rate_ctr: " $D3 }, \ 0xc0 { "entry_poll_tmr: ap: " $D1 " poll_state: " $D2 " io_rate_ctr: " $D3 }, \ 0xc1 { "poll_mode_on: ap: " $D1 " poll_state: " $D2 " io_rate_ctr: " $D3 }, \ 0xc2 { "poll_mode_off: ap: " $D1 " poll_state: " $D2 " io_rate_ctr: " $D3 }, \ \* { "Unknown sub-opcode. Verify." } Here is a sample output: 3B9 wait 0 131077 2.224288 FCDD entry_intr: ap: F1000A0150610000 3B9 wait 0 131077 2.224418 FCDD command_in: ap: F1000A0150610000 ctl_elem: F1000A002735DDE8 iocb: F1000A01505933C0 ring: 0001 3B9 wait 0 131077 2.224424 FCDD exit_intr: ap: F1000A0150610000 har: 0080
