I have Bionic Beaver, kernel 4.15.0-20-generic #21-Ubuntu on an MSI GE60 laptop with the following Ethernet controller:
Qualcomm Atheros Killer E220x Gigabit Ethernet Controller (rev 13)
After a random period of time (especially when I do an RDP session), the kernel starts flooding /var/log/syslog with gigabytes of the following text (hundreds lines per second):
May 17 10:08:07 mylaptop kernel: [ 9444.580988] alx 0000:03:00.0 enp3s0: fatal interrupt 0x4001607, resetting
The entire system gradually stops responding, one of the processor cores is 100% busy and the power-off button is the only way out. I know the problem emerged a couple of years ago, and was impossible to solve then (eg Ubuntu 15.04: eth0 is no longer working after last software upgrade). My question is, could I install another Ethernet card driver by apt instead of alx?
Important: I cannot use the wireless connection.
