Title:
5.4.0-1011-raspi flooding kernel.log and syslog with failed driver
events
Status in linux-raspi package in Ubuntu:
New
Bug description:
As described here (this is not my post):
https://askubuntu.com/questions/1242733/kern-log-and-syslog-growing-uncontrollably-with-details
The new kernel flooding the kernel.log and syslog files rapidly until
there is no more space and sometimes make the raspberry pi
unresponsive. I just downgraded and hold the 5.4.0-1008-raspi kernel
until the bug has been fixed.
This issue is really critical for me and others.
I truncate the files in order to keep my system running normally but
they reach the Gb mark in minutes. I attached both syslog and
kernel.log in a trimmed version.
