and its frozen on this screen

i will also include the image i took when installing:
i couldn’t upload another image so ill upload it here

Steps to Reproduce

  1. Update bios

  2. Boot into the os

Expected Behavior

Booting normally

2

The driver is hanging the boot process, used nomodeset flag to bypass
something must have changed between v2512 and v2606 in the graphics or smth

@MrChromebox can you help?

3

there are almost zero changes for StoneyRidge in this release other than the new edk2 payload

4

well it isnt working and only thing getting it to boot is setting nomodeset
when i do it w/o it it just freezes with the small pink stripe,
also is there any archive of images so i can flash the older coreboot version?

5

sigh, the release notes literally tell you to make a backup before updating to any new release, esp a big one like this

barla uses the careena iamge:
