on two of our systems, lfs has taken on killing the kernel within
seconds of boot; there is no way to use the systems sensibly anymore
other than mounting the lfs partitions read-only.
What I get is:
| lfs_segwrite: possibly invalid checkpoint!
| lfs_segwrite: ifile still has dirty blocks?!
| bp=0xca38e3e8, lbn 21, flags 0x24080
| bp=0xca37c5f8, lbn 20, flags 0x24080
| panic: dirty blocks

The only thing I can see is that the filesystem filled to over 90%
before that happened; there are no other peculiar things that were
happening on that machine.
Unfortunately, I can't keep the machines in this state to do any tests
or trials on; I will be converting the partitions back to ffs today in
order to have the systems running again.
