Description core.dumped.sm 2013-05-14 06:30:00 UTC 
I am using Asus USB-N11 wireless card as host AP:
ugen4.2: <802.11 n WLAN Ralink> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0200 
  bDeviceClass = 0x0000 
  bDeviceSubClass = 0x0000 
  bDeviceProtocol = 0x0000 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x1761 
  idProduct = 0x0b05 
  bcdDevice = 0x0101 
  iManufacturer = 0x0001  <Ralink>
  iProduct = 0x0002  <802.11 n WLAN>
  iSerialNumber = 0x0003  <1.0>
  bNumConfigurations = 0x0001 
Regularly there are unpredictable reboot because of problems with the device driver:

How-To-Repeat: Plug Asus USB-N11 device.
Configure the system to use the device as a host AP.
Wait indefinitely: sometimes a kernel panic occurs without any connection to the host AP.

Responsible Changed
From-To: freebsd-bugs->freebsd-net

Over to maintainer(s).
Comment 2 PseudoCylon 2013-05-19 03:01:54 UTC 
This must be the same bug as kern/153938
http://www.freebsd.org/cgi/query-pr.cgi?pr=153938&cat=
and patched at rev. 218676
http://svnweb.freebsd.org/base?view=revision&revision=218676

Please upgrade to 9.1-RELEASE or backport.

Comment 3 core.dumped.sm 2013-06-18 12:39:47 UTC 
Major upgrade for a system with a set number of ports around 2k is not
acceptable for me.
I updated system to the last release - 8.4, Ánd replaced system files on
similar of the link:
http://svnweb.freebsd.org/base?view=revision&revision=218676

Comment 4 PseudoCylon 2013-06-18 21:53:02 UTC 
Try removing the line 77 in if_run.c

Since r236486, nitimes() is defined in sys/param.h

Comment 5 core.dumped.sm 2013-06-19 11:49:38 UTC 
The build kernel was completed. Thanks!
Will wait for a panic.

The problem disappeared. Can make a commit to the releng 8?
Comment 7 Eitan Adler freebsd_committer freebsd_triage 2017-12-31 07:58:45 UTC 
For bugs matching the following criteria:

Status: In Progress Changed: (is less than) 2014-06-01

Reset to default assignee and clear in-progress tags.

Mail being skipped
Comment 8 Andriy Voskoboinyk freebsd_committer freebsd_triage 2018-12-18 04:41:45 UTC 
I don't think that MFC for run(4) commits to 8-RELEASE is still needed (and it's unsupported anyway).
