Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE. Can you verify if the problem persists on 10.2-PRERELEASE? Created attachment 158658 [details]
core crash summary: 10.2-BETA1
I confirmed that this is still an issue with 10.2-BETA1.
(In reply to Nikolai Lifanov from comment #3) > #8 0xffffffff8058773a in iwn_tx_data (sc=0xfffffe0000974000, > m=0xfffff80011f97000, ni=0x0) at /usr/src/sys/dev/iwn/if_iwn.c:3546 > ni=0x0 IMHO, this is not iwn issue. Fixed in r288990; I will close this PR after MFC. *** Bug 205169 has been marked as a duplicate of this bug. *** *** Bug 195042 has been marked as a duplicate of this bug. *** A commit references this bug: Author: avos Date: Sun Nov 6 16:44:33 UTC 2016 New revision: 308376 URL: https://svnweb.freebsd.org/changeset/base/308376 Log: MFC r288990: Fix regression from r248371.

Created attachment 149487 [details] core summary for the crash I get a reproducible panic on 10.1-RELEASE with iwn (does not panic on 10.0-RELEASE or the wired interface) when starting Pidgin v2.10.10 from official pkg repository. I'm attaching crash summary.
