panic: filesystem goof: vop_panic[vop_revoke]

[Xiao-Yong Jin]

Hi, sadly, I encountered a kernel panic this afternoon.  I was
transferring a file from remote host, and it happened.

Sep  8 13:06:13 presario kernel: info: [drm] writeback test succeeded in 1 usecs
Sep  8 16:53:40 presario syslogd: kernel boot file is /boot/kernel/kernel

1. What do I need to further investigate the reason for the panic?
2. How can I find the file referred in the fsck out put?
3. If someone wants to improve the quality of FreeBSD and wants me to
   give more information, I'm willing to.  Just send me a message.

Thank you,
Xiao-Yong
