[Pro 7/Laptop 3]: Kernel panic at boot due to incorrect BAR specification for intel-lpss-pci #12
Description
Description (taken from LKML):
Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci
in MTRR. This will cause the system to hang during boot. If possible,
this bug could be corrected with a firmware update.
Upstream LKML: https://lkml.org/lkml/2019/10/16/1230
Upstream bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203485
Workaround: Blacklist intel_lpss_pci, if necessary via kernel parameter
