Then, compile trace-cmd (https://git.kernel.org/cgit/linux/kernel/git/rostedt/trace-cmd.git/) Finally as root: trace-cmd record -e iwlwifi -e iwlwifi_dbg Run the failing scenario - until you get the warning. you'll get a trace.dat file. Compress it and send it to me. If you can't make it work - please enable CONFIG_IWLWIFI_DEBUG and load the iwlwifi module with: debug=0xC0800000 and send the dmesg output / syslog when the WARNING occurs. This option is less preferred though. > > On Sat, Jan 18, 2014 at 2:43 PM, Emmanuel Grumbach <egrumbach@xxxxxxxxx> wrote: >> >> >> On 01/18/2014 08:47 PM, Adam Stylinski wrote: >>> So does kernel 3.13 address all of these stability issues I've been >>> having with the 7260 wireless NIC?
