Hi,

I've just wanted to test openwrt-21.02 (with ath10k-firmware-qca4019 + kmod-
ath10k) on an Plasma Cloud PA1200 router. While this device worked fine in the 
past, with this upgrade (to the newest firmware from linux-firmware), the 5GHz 
radio firmware seems to crash whenever I set it up via `ifconfig wlan1 up`:

    ieee80211 phy1: Hardware restart was requested

Interestingly, the crash disappeared when I've changed 
baseEepHeader.nonLinearTxFir (offset 0xc2 in the BDF) from 1 to 0.

The device itself was using firmware 10.4-3.6-00140 (the version currently in 
linux-firmware) - a working firmware is 10.4-3.5.3-00078. I also wanted to 
"bisected" when this problem was introduced but there are only these two 
recent firmware version available in Kalle's ath10k-firmware repository.

Does anybody know more about it?

Kind regards,
	Sven
