Fixed in -current. If you have a debugging kernel, go into gdb on the kernel.debug file, and print the code at: > #6 0xc0213723 in generic_bzero () > #7 0xc01cfef7 in ffs_vget (mp=0xc4c11800, ino=22283597, > vpp=0xf96f9d48) at ../../ufs/ffs/ffs_vfsops.c:1109 And then look at the same source code in -current to see the fix. Sorry, I don't have your exact version of the source code, so I can't do this for you. -- Terry
