gstammw: Bug confirmed on OpenWrt 21.02.0 FINAL
|
gormih: [ 0.000000] Linux version 5.4.154 (builder@buildhost) (gcc version 8.4.0 (OpenWrt GCC 8.4.0 r16325-88151b8303)) #0 SMP Sun Oct 24 09:01:35 2021 ...... [90427.178591] mt76x2e 0000:01:00.0: Firmware running! |
laigor: Logged kernel panic: |
laigor: I compile 21.02 with fresh mt76 dated 2022-01-31 and the problem is gone. |
Hi, |
Both official 21.02.5 and official 22.03.2 are broken. But as mentioned above, building with mt76 from around 2022-01-31 likely fixes this bug. At least my 4a is fine for 6+ days whereas the previous best was around 3 days before the bug occurrence. |
Hey!, do you know how to apply this patch? |
Follow the guide. Use v21.02.5 instead of v21.02.3. In menuconfig you may want to enable luci -> collections -> luci as well as more non-essential packages if you need then. |
Thank you very much for helping me, the patch is working for me! |
This patch is needed for 22.03? |
I am getting the same error on 2.4G wifi. [ 93.179112] mt76x2e 0000:02:00.0: MCU message 02 (seq 15) timed out |
I got fixed creating a one 2,4/5Ghz with SSID using the same name and turning off the DNS in my network. I don't know what be the root cause, but maybe help anyone. |
@webysther does it fix the problem of 5Ghz breaking, or just helps clients to downgrade to 2.4 and keep going? |
To follow |
@dvalter fix the problem to me, try using the same SSID for both. |
I tried switching the 2.4G and 5G to the same SSID and rebooting, |
23.05.0-rc1 |
Tried running 22.03.5 with 2.4+5 and the same SSID, got an unpleasant experience with clients switching from 2.4 to 5 and back |
