Hello,
the recent changes in vfs_cluster.c, buf.h and ffs_alloc.c cause a
panic on my SMP-System.
This is the commitlog of the changes:
dg 1998/11/12 17:01:45 PST
Modified files:
sys/kern vfs_cluster.c
sys/sys buf.h
sys/ufs/ffs ffs_alloc.c
Log:
Restored the "reallocblks" code to its former glory. What this does is
basically do a on-the-fly defragmentation of the FFS filesystem, changing
file block allocations to make them contiguous. Thanks to Kirk McKusick
for providing hints on what needed to be done to get this working.
Revision Changes Path
1.72 +4 -15 src/sys/kern/vfs_cluster.c
1.61 +15 -1 src/sys/sys/buf.h
1.54 +4 -14 src/sys/ufs/ffs/ffs_alloc.c
Backing out these changes solves the problem.
The panic is"ffs_blkfree: bad size"
mp_lock=01000001; cpuid=1; lapic_id=01000000
This is the Stacktrace:

The panic is reproducable with a make -j4 world. I do have a dump!

In this case I was not using softupdates. The panic appears with and without
async mounts of the filesystems.
