Maybe ASPM - check for kernel option:
Code: | $ zgrep ASPM /proc/config.gz | grep =
CONFIG_PCIEASPM=y
CONFIG_PCIEASPM_PERFORMANCE=y |

Updating the kernel might mean updating the firmwares to versions the new kernel need to work proprely. For example, a Linux source from the testing branch (~) can need the linux-firmware of the testing branch too, not the stable version.
So, accorging to the kernel log, are you sure that your graphic and other drivers did'nt complain about missing firmwares and versions? _________________ Paul |

Maybe something with Frequency scaling. Check for :
Code: | CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
