Title:
very slow boot with new kernel 5.3.0-51
Status in linux package in Ubuntu:
Expired
Bug description:
I already reported the but using "ubuntu-bug linux" but could see
nowhere to tell you what the problem actually was. In summary it is
relatively new system, 18.04.4LTS 64bit and Maté 1.20.1 dual-booting
with Windows 10 v.1909, built on a Gigabyte Aorus B450M mainboard,
Ryzen 5 3400G with Radeon Vega Graphics × 8, Kingston A2000 M2 main
drive and a supplementary 4TB data drive. A wired connexion to BT Hub
6 via BT Powerline is used and gives no trouble on any other system.
The system started with kernel 5.3.0-46 generic and was fine for a few
months, booting in a few seconds. A couple of days ago the kernel
upgraded itself to 5.3.0-51 generic and boot immediately became a
minute or more.
Reverting to kernel 5.3.0-46 generic restores the fast boot time.
I can continue like this for a while but my main fear is that when the
LTS update to 20.04 arrives the new kernel will contain the bug and
reversion to 5.3.0-46 will no longer be possible.
I attach several files, tarred because you do not seem to provide the
facility to attach more then one file. There are a copy of the current fstab,
the output of hwinfo (taken with kernel v.51) and for each of the two kernels
the data asked for on the Ubuntu website.
