Hi, since v5.5-rc1 the google kevin chromebook does not boot. Git bisect reports 5e0c21c75e8c PCI/ASPM: Remove pcie_aspm_enabled() unnecessary locking as the first bad commit.
In order to revert it from v5.5-rc1 i had to also revert some dependencies: 5e0c21c75e8c08375a69710527e4a921b897cb7e aff5d0552da4055da3faa27ee4252e48bb1f5821 35efea32b26f9aacc99bf07e0d2cdfba2028b099 687aaf386aeb551130f31705ce40d1341047a936 72ea91afbfb08619696ccde610ee4d0d29cf4a1d 87e90283c94c76ee11d379ab5a0973382bbd0baf After reverting all of this, still no luck. So, either the results of git bisect are not to be trusted, or there are more bad commits.
By "does not boot" i mean that the display fails to start and the display is the only output device, so debugging is quite difficult.
v5.5-rc1 as is (reverting no commits at all) works fine when disabling PCI: # CONFIG_PCI is not set
Regards, Vicente.
