Title:
Linux 5.4.0-105 breaks Bluetooth and makes system too slow to use
Status in linux package in Ubuntu:
Fix Released
Bug description:
Currently running this kernel which is working fine:
Linux 5.4.0-104-generic #118-Ubuntu SMP Wed Mar 2 19:02:41 UTC 2022
x86_64 x86_64 x86_64 GNU/Linux
Immediately after installing the latest kernel update to Linux
5.4.0-105 and rebooting, the following error is printed endlessly to
console multiple times per second by Bluetooth hci:
Malicious advertising data. Stopping processing
I don't have the exact log because my system was unusable beyond
reading the console and I had to force reboot, but that was definitely
the message that was printed.
I have no Bluetooth devices powered on when booting (just my laptop's
adapter I guess).
The system is also too slow to do anything, I have to force reboot.
Reverted to kernel 5.4.0-104 and problems are gone.
See the lspci-vnvn.log but keep in mind that I generated it on the
working 5.4.0-104 kernel, as it was impossible to do anything on
5.4.0-105.
