5.4.0-80-generic panics with Toughbook CF-T8 4

[Yvan Masson]

Hi,

The Panasonic Toughbook CF-T8 4 can not boot (kernel panics) with 5.4.0-80-generic on Lubuntu 20.04. However, it works perfectly with 5.4.0-53-generic. I will try with current HWE kernel and let you know.

Regards,
Yvan

Hi,

Please apologize, I have just seen that 5.4.0-81-generic was available: this computer now boots properly again.
