>How-To-Repeat:
Export a file system (haven't had time to test whether this is NTFS specific, as both FFS, NTFS and FAT file systems are exported) from a FreeBSD 4.10 machine (freshly after a build world) to a Solaris 8 machine (SunOS blackhole 5.8 Generic_108528-23 sun4m sparc SUNW,SPARCstation-20). Attempt to do ls on the directory -- kernel panic occurs. The kernel panic repeated itself next time, so I had to do a forceful unmount on the Solaris side.
