Well euhm.. that was not enough :( mounting goes ok now but i get another
panic:
panic: pool_get: biopl: page empty
pool_get + 0x251 (i386)
getiobf1
getiobuf
lfs_newbuf
lfs_initseg
lfs_seglock
lfs_valloc
ufs_makeinode
....
lfs_create
....
Running with DIAGNOSTIC+DEBUG+LOCKDEBUG, the kernel immediately crashes
when reading when it starts syslogd:
pool_get: bufpl: curpage NULL, nitems 7
panic: pool_get: nitems inconsistent
trace:
pool_get +0x1a5 (i386)
getnewbuf
getblk
bio_doread
bread
ffs_vget
ufs_lookup
VOP_LOOKUP
lookup
namei
sys_access
...
So somthing is definatively wrong in the pool code :-/ also the `bp->b_vp =
NULL;' would help on other places.
Happy hacking :)
