description |
Fail to boot into Ubuntu GRUB on the platforms which legacy(8254) timer function is disabled.
"8254 clock gating" is provided to disable 8254 timer to get rid of legacy and save power. The platforms with the firmware which disable the 8254 timer will fail to boot up and block on grub2 which uses the 8254 timer to calibrate the TSC. |
[Impact]
Some Intel SoC-based systems.
[Test cases]
1) Boot an affected system.
[Regression potential]
Some systems may rely on the current state of the timer selection in order to be able to boot successfully, or to catch key presses before the end of a timeout in the menu.
These systems may then fail to boot correctly, stuck in a timeout of crashing in grub. The new default, pmtimer, should be available on all ACPI-capable systems without being power-gated such as for the PIT, so the impact of this possible regression is minimal.
