I am using Ookhla Speed Test for all the speed tests(I have 100mbps symmetrical bandwidth connection) .
Previous to the 22.03.0-rc1, I was running 22.03.2 release on my Archer C50 V3 and I am pretty much sure it had no issues with 2.4Ghz wireless radio. I might go back to that version to further verify the fact.
And the same 22.02.2 was running on my R6220. R6220 had the issue with 2.4Ghz and a weird issue with Realtek FE(10/100mbps) R6220 issue with FE Lan devices. But with the 22.03.0 R6220 seems pretty stable and consistent for all the 2.4ghz, 5Ghz and LAN interface.
Its like the problems I had with Netgear R6220 with OpenWrt 22.02.2 is now the problems I have with OpenWrt 22.03.0-rc1 on Archer C50; minus the FE Lan issue. But I still need to verify once more all that I said.
And in both the router with 22.03.0-rc1 nlbwmon along with software flow offloading does not work(pretty much sure and tested).
TL;DR:- OpenWrt 22.03.0-rc1 stable on R6220 and have issues on Archer C50
do_page_fault(): sending SIGSEGV to ujail for invalid read access from 00000036

I'm seeing this on a Totolink X5000R (ramips/mt7621) shortly after startup.
On openwrt 22.03.0-rc1 for BT Home hub 5, I get the follwing results:-
1 It takes 4 or 5 re-starts to actually boot into 22.03.0-rc1
2 When in, I have to connect via wired to actually obtain wireless
I have reverted back to stable 21.02.3 & hope these errors are corrected in 22.03.0-rc2. I can then resume testing.
