Thanks to all the OpenWrt developers.

Six hours up
and
All appears to be fine on a Archer C2600 v1.1 with BanIP, Adblock and irqbalance.

There's a regression on TP-Link TL-WDR4900 v1 (mpc85xx/p1010). Wifi is down after upgrade. It looks like from the 21.02.3 -> 21.02.4 upgrade, but still in 21.02.5 - see https://github.com/openwrt/openwrt/issues/11002 for details. Workaround is to manually fixup /etc/config/wireless and then remove or edit /etc/hotplug.d/ieee80211/05-wifi-migrate

Modem-manager is not working well on 21.02, I backported a series of fixes: https://github.com/openwrt/packages/pull/19648 for it which I hope will be included in the next service release.

Probably a last maintenance release just before the end-of-life in April 2023.
(just a guess)
