Yes. With linux boot enabled, I can get into system just need many retries, not stable, maybe 10-20. Without linux boot, when grub start loading, nearly immediately reboot. I tried add "debug ignore_loglevel" to linux boot argument, but the grub boot message is not readable. It shows on top part of screen and being show as 3 splited micro screen, the message keep scrolling within microscreen, don't kown how to fix this.
