The Internet disappears (red wi-fi indicator) and the system freezes (almost always).

Default kernel.

The first dmesg block is when the system has been running for some time (from a minute or more), and then it stops.
And the second dmesg block is when wi-fi stops working immediately during startup session.

Additional info:

Reporting a bug with an obsolete kernel doesn't really help.

Edit: damn, I thought this was new. My appologies.

I can confirm it on
$ uname -r

and (TP-LINK TL-WB722N v1
$ lsusb
Bus 001 Device 005: ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n

I assume, the issue is related to the driver, because other distros are affected, too:

Under heavy load, the driver died.

We should move the discussion to
because the arch maintainer can do nothing to solve it.
