penalvch, later today internet download speed became significantly reduced -- although connectivity was not lost. I looked in dmesg to see the following trace repeating over and over again:

However, once restarted, download speed went back to normal. Perhaps the updated 7260 firmware is required as well as the fix to the kernel? Would you like me to re-apply the new firmware? I apologize for this, just when I thought we had everything stable...
