It's obvious now you say it ;-)
You are indeed right:
(kgdb) frame 9
#9 0xffffffff8067d3ee in uma_zalloc_arg (zone=0xffffff00bfed07e0, udata=0x0,
flags=-256) at /usr/src/sys/vm/uma_core.c:1835
1835 uma_dbg_alloc(zone, NULL, item);
(kgdb) p *zone
$1 = {uz_name = 0xffffffff808084cd "FFS inode", uz_lock = 0xffffff00bfecf7f0,
uz_keg = 0xffffff00bfecf7e0, uz_link = {le_next = 0x0,
le_prev = 0xffffff00bfecf830}, uz_full_bucket = {
lh_first = 0xffffffe01a74c830}, uz_free_bucket = {
lh_first = 0xffffff00469bf830}, uz_ctor = 0x6400000000, uz_dtor = 0,
uz_init = 0x9a00000000, uz_fini = 0, uz_allocs = 17180460407,
uz_frees = 504673, uz_fails = 0, uz_fills = 0, uz_count = 128, uz_cpu = {{
uc_freebucket = 0xffffff000e5d6830, uc_allocbucket = 0xffffff003a5f7000,
uc_allocs = 97, uc_frees = 0}}}
Now what does that mean??
I just experienced another panic, but it failed to writ to disk
:-(. I will force another one and check that the details are the same.
