I've tried old kernel when just spotted this issue, but with the old kernel and new world I wasn't able to use ppp so I gave up on that quickly. Back then I haven't had dumpdev configured so wan't able to save a dump. Anyways, in the end I've tried different various kernels, including 8.0 kernel and world but was still having problems with writing stuff to disk. Finally, I've did a reinstall of 8.0 with newfs for all partitions and it now works fine, so probably the fs was damaged somehow.
