Package: firmware-misc-nonfree Version: 20190114-2 kernel module: mt76x0 Severity: serious Following an update recently, this driver stopped working correctly. I can now only get a working WiFi connection for a few seconds after reboot, or after waiting several minutes, making anything that requires the internet almost impossible. This was working fine until the update. Once the interface is up, the driver crashes almost immediately. It does not matter whether I use NetworkManager or do things manually with /etc/network/interfaces and then ifup. The same trace is seen in the logs and dmesg repeatedly. I have ruled out hardware issues. uname -a : Linux hope 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux # modinfo mt76x0 filename: /lib/modules/4.19.0-16-amd64/kernel/drivers/net/wireless/mediatek/mt76/mt76x0/mt76x0.ko license: GPL firmware: mediatek/mt7610u.bin alias: usb:v0E8Dp7650d*dc*dsc*dp*icFFisc02ipFFin* alias: usb:v0E8Dp7630d*dc*dsc*dp*icFFisc02ipFFin* alias: usb:v2357p0105d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0DF6p0079d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v7392pC711d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v20F4p806Bd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v293Cp5702d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v057Cp8502d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v04BBp0951d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v07B8p7610d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0586p3425d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v2001p3D02d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v2019pAB31d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0DF6p0075d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0B05p17DBd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0B05p17D1d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v148Fp760Ad*dc*dsc*dp*ic*isc*ip*in* alias: usb:v148Fp761Ad*dc*dsc*dp*ic*isc*ip*in* alias: usb:v7392pB711d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v7392pA711d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0E8Dp7610d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v13B1p003Ed*dc*dsc*dp*ic*isc*ip*in* alias: usb:v148Fp7610d*dc*dsc*dp*ic*isc*ip*in* depends: mac80211,mt76,cfg80211,usbcore retpoline: Y intree: Y name: mt76x0 vermagic: 4.19.0-16-amd64 SMP mod_unload modversions sig_id: PKCS#7 signer: Debian Secure Boot CA sig_key: 4B:6E:F5:AB:CA:66:98:25:17:8E:05:2C:84:66:7C:CB:C0:53:1F:8C sig_hashalgo: sha256 signature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elevant extract from dmesg: [ 996.874969] mt76x0 1-5:1.0: Error: send MCU cmd failed:-71 [ 996.875010] mt76x0 1-5:1.0: Error: MCU response pre-completed!
