kernel panic (ffs_valloc)

[Matthew Dillon]

:Hi, I'm trying to install gmake.
:But every time when I do "make" inside "/usr/ports/gmake", I got
:a kernel panic. Here is the output:
:
:mode = 0120755, inum = 430204, fs = /usr
:panic: ffs_valloc : dup alloc
:Debugger("panic")
:Stopped at  Debugger+0x34: movb $0, in_Debugger.342
:db>
:

:Anyone has any idea? Thanks!

    Boot into single user and do a manual 'fsck'
