As I said, I had such a USB stick with Arch Linux installed, and it worked there just fine. In fact, I tried just now (to make sure, though with a recovery drive, uses isolinux), and it's ok. Note there are really 3 levels of "working":
1 - works flawlessly - only VM for this pen 2 - initrd doesn't recognize the disk on the 1st attempt to mount root, works after waiting a few seconds and trying again (not waiting enough gives an error again) 3 - initrd doesn't recognize the disk ever (I went up to 5 mins, sounds more than enough) That PC is in 3. But any other disk I tried so far works. And I never had this error before, with any sort of pen, including the Gentoo recovery/install pen which supposedly uses genkernel as I do here, but somehow initrd always works with it (case 1). The fact that 2 does happen for every other PC says there is actually something awry, but I think it's with the initrd. The thing is that BIOS knows the pen is there, syslinux also detects it right away and knows where the root partition is with UUID, and still the initrd can't figure it out right away?
