Hi all,

Later I noticed that it is reported from #coreboot that linux needs "acpi=noirq" to boot properly

Hi Heymans,

Today I performed a test on my x230, which shows that commit d2d2aef6a3222af909183fb96dc7bc908fac3cd4 ( https://review.coreboot.org/23287 ) renders keyboard unable to operate under Heads, too. The regression seems not only affect hp 810g1.

The tests below are performed on my 810g1, for its spi flash is easy to access:

  1. Grub payload: complete stalls after the menu gets shown on the screen.
  2. SeaBIOS: Keyboard can be used to operate SeaBIOS and grub-pc, but linux kernel booted from it behaves ill: a log "rtc_cmos: hctosys: unable to read the hardware clock." is printed, and rootfs on hdd cannot be mounted.

The coreboot config used to build the ill image from HEAD revision with grub payload is attached, within which some hints might be found.
