freeze in vfs on DragonFly-CURRENT?

[Matthew Dillon]

:  Hello!
:I have last (some days ago compiled) DragonFly-CURRENT and got too
:many freezes. Seems to freeze in vfs code.
:
:Kernel and crash dump can be found at:
:http://snug.org.ua/deep/

    Ok, I downloaded and examined the crash dump.  I do have to add a
    check in the code but the only path I see that could cause the 
    crash is if the block device underlying a filesystem is removed
    without first unmounting the filesystem.  The kernel is not going
    to be happy with that sort of situation even when I fix this particular
    panic point.

    The filesystem your panic occured on in this case was /dev/ad1s1d,
    mounted on /var.  Somehow ad1, ad1s1 or ad1s1d is becoming invalid
    while the filesystem is still mounted from ad1s1d.
