I followed the instructions above and linux-next-20220930 booted on the QDrive3 to a prompt. It then hanged after a couple minutes and rebooted in Sahara mode: B - 1662280 - Sahara Init B - 1665422 - Sahara Open There seems to be no trace from the kernel, this happened consistently over 3 boots. I asked Brian, he mentioned he only booted to prompt so that may have happened unbeknownst to him as well. -- Eric Chanudet
