Subject:   Panic (malloc: wrong bucket) in smbfs
Message-ID:  <20010618122417.G76256@kirk.sector14.net>

I mounted a WinNT share and then tried to mount a second one from a
machine which wasn't finished booting yet.  I'm not yet sure which
caused the panic; I'll provide more details if/when I bump into
them... but what I can provide now is a copy of a gdb -k run with
backtrace.  This is 4.3-STABLE as of Saturday (6/16/01) on a 200 MHz
Pentium with 32 meg of RAM (soon to be more if I can help it) and IDE
drives.
