Details

Description:
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:

dmesg:

ath: phy0: Chip reset failed
ath: phy0: Unable to reset channel, reset status -22
ath: phy0: DMA failed to stop in 10 ms AR_CR=0xffffffff AR_DIAG_SW=0xffffffff DMADBG_7=0xffffffff

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
5.9.14-arch1-1

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 bugzilla.kernel.org
https://bugzilla.kernel.org/show_bug.cgi?id=207397
because the arch maintainer can do nothing to solve it.
