Description

tested with coreboot 717c0505b1063da72db9aba2f1f0e1ef6dee60da
Works:

  • uefipayload_2511
    Broken:
  • uefipayload_2608

Seems to hang in payload. Since there's no RS232 serial available, only EHCI debug works, it's not clear why it hangs.

HEAD of current edk2 branch (1f9ab463057c53883245d0ce5dfe07201efb1efe) or latest tag (26.09.2, afe0e87d25d5ac57191aa7c5211c83d1c13d198f)?

Leah is using 26.09.2 for libreboot currently, and says it works fine on her x220.

It seem to hang after the GRUB menu. Probably around ExitBootServices or RuntimeVariable usage.

I'll try to get serial logs out of it.
My idea was to log to CBMEM and use a watchdog to reset the system, though TCO watchdog doesn't work yet.
