--- Comment #2 from emz@norma.perm.ru ---
Got panic on r332466:

Apr 18 17:52:39 san1 kernel: vputx: usecount not zero for vnode
Apr 18 17:52:39 san1 kernel: 0xfffff80f4d7d1760: tag devfs, type VCHR
Apr 18 17:52:39 san1 kernel: usecount -1, writecount -1, refcount 0

Only these lines in the messages, no crashdump this time (although I was
getting decent crashdumps previously).

Cannot find much aboth this kind of panic, what does it mean ?

Am I right assuming that the last panic is related to the
https://svnweb.freebsd.org/base?view=3Drevision&revision=3D331666 ?

(Is this PR a right place to continue the discussion ?)

I'm on FreeBSD 11.1-RELEASE with a SAS9300-8e card. Any time mprutil is =
invoked, the kernel logs:

mpr0: mpr_user_pass_thru: user reply buffer (64) smaller than returned =
buffer (68)

Attempting to use mprutil to do a firmware upgrade fails with:

mpr0: mpr_user_command: unsupported parameter or unsupported function in =
request (function =3D 0x9)



Is this a mismatch between driver/tools and firmware, or some other =
problem?
