FS#1530 - r6755: tl-841n-v8 problems: ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 ... #6483
Comments
adrianschmutzler: Does this still happen for master or 19.07? What about ath79 vs. ar71xx? |
glycoknob: @adrian: Still seeing this in crashlogs with OpenWrt 19.07 on 1043nd v1 |
glycoknob: this is from around may 2020 with 19.07

Started to see these errors in crash-reports - seems to happen multiple times per day.
