Description Rene Petersen 2024-05-26 14:16:49 UTC

Hey guys,

similar to Oleksandr Natalenko's recent MT7915e issue (https://lore.kernel.org/regressions/6061263.lOV4Wx5bFT@natalenko.name/) I'm facing the same problems with MT7615e driver (WiFi card won't be loaded since v6.9).

OS: Arch Linux (Arch Vanilla Kernel)

MT7615e logs while loading: http://0x0.st/XZGN.txt

We tried to apply the fix for MT7915e to MT7615e (https://github.com/torvalds/linux/commit/2f7cf3b61d85228ae749b6cb8eda1e1df9d4926f) and it's working again (see also: https://bbs.archlinux.org/viewtopic.php?pid=2173726 Post#17 + Post#18).

Thanks in advance! Have a nice day ;)

Johannes,

I'm a no one but it would be great if 2f7cf3b61d85228ae749b6cb8eda1e1df9d4926f was pushed to stable, thank you.

2f7cf3b61d85228ae749b6cb8eda1e1df9d4926f has already been pushed to stable. It does not fix this issue which is for the mt7615 not the fixed mt7915. Making the same four line change but to drivers/net/wireless/mediatek/mt76/mt7615/main.c as has been made in drivers/net/wireless/mediatek/mt76/mt7915/main.c has been found to fix this issue.

Fix is available in master. See: https://github.com/torvalds/linux/commit/40cecacabc46
