FS#4051 - ath10k_pci firmware is crashing in loops

I have a TP-Link Archer C7v4 with 21.02. After 21.02 upgrade, ath10k firmware started to crash in loops. I get a lot of logs,

[11487.634801] ath10k_pci 0000:00:00.0: device successfully recovered

And a couple of kernel stacks too. I’ll attach dmesg messages.

It started after my last reboot and system uptime is still small (about 3hs).
The system seems to be updated:
ath10k-board-qca988x - 20201118-3
ath10k-firmware-qca988x-ct - 2020-11-08-1
kmod-ath - 5.4.143+5.10.42-1-1
kmod-ath10k-ct - 5.4.143+2021-06-03-b44cd7b2-2

ath9x does not seem to be affected.

After a reboot, the system was stable again.

It crashed again and again. Is this a HW problem?
