           Summary: ath9k causes computer to hang
           Product: Networking
           Version: 2.5
     KernelVersion: 2.6.27-7-generic
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Wireless
        AssignedTo: networking_wireless at kernel-bugs.osdl.org
        ReportedBy: barry at lemonpi.net


Latest working kernel version:N/A
Earliest failing kernel version:2.6.27-7-generic
Distribution:Ubuntu 8.10
Hardware Environment:Athlon 64 X2 5600+.  Linksys WMP300N PCI card, Linksys
WAG325N Wireless-N router.
Software Environment:compat-wireless-2008-11-26

Problem Description:

After doing a "sudo modprobe ath9k", the system will continue to run for just
under 3 minutes.  I start a ping to the local router, which reports destination
unreachable for a couple of minutes, then starts to respond.  About 10 seconds
after it starts to respond, the whole system hangs.  Video freezes, no
mouse/keyboard, no disk activity, and I have to do a hard reset.  The last time
I tested, the Linksys router actually crashed at the same time and I had to
hard reboot it too.  This has only happened once though, so may have been a
coincidence (hell of a coincidence though).

Steps to reproduce:

- Blacklist ath9k so that it doesn't freeze the computer on startup.
- Do "sudo modprobe ath9k".

I get the same problem whether I'm using WPA2 encryption, or no encryption at
all.
