Hi Everyone, Attached is a dmesg for a Fedora 33 machine that went sideways tonight after a 'dnf upgrade' and reboot. The machine is a low-end Cherry Trail. It boots but something broke with the USB modem. The error message is " Failed to open device /dev/ttyACM0: No such file or directory". The dmesg is full of: [ 14.970968] es8316 i2c-ESSX8316:00: ASoC: error at soc_component_write_no_lock on i2c-ESSX8316:00: -121 [ 14.976669] es8316 i2c-ESSX8316:00: ASoC: error at soc_component_write_no_lock on i2c-ESSX8316:00: -121 [ 15.008046] es8316 i2c-ESSX8316:00: ASoC: error at soc_component_write_no_lock on i2c-ESSX8316:00: -121 [ 15.008166] es8316 i2c-ESSX8316:00: ASoC: error at soc_component_write_no_lock on i2c-ESSX8316:00: -121 What kernel component should this bug report be filed against? Thanks in advance.
