Since 4.3 was released today, I decided to give it a shot.... same result: hangs while/after loading bzroot. For some strange reason, I decided to boot the kernel without a rootfs. Hit TAB in syslinux, removed initrd=bzroot from the kernel cmdline. BOOTS! This verifies 2.6.24.4-unRAID kernel boots fine on my metal, even without any of: noapic, nolapic, apic=off. At this point I'm convinced it's the rootfs image or syslinux itself. After about an hour of rolling my own initrd image with no progress, I decided to check if there's a newer syslinux at http://www.kernel.org/pub/linux/utils/boot/syslinux/. I grabbed syslinux-3.63.zip pulled out syslinux.exe, ran syslinux -ma d: on my 4.3 stick. SUCCESS!

Thanks for the suggestions! I tried them all but none worked. I swapped USB flash keys, same problem, so that tells me the keys are prepared properly (HP format tool, -ma, fat32, etc) Summary: #1 ASUS A7N8X-E Deluxe (nForce2), 1GB -- both 4.2.4 and 4.3b6 work fine. #2 ASUS P5N32-SLI Deluxe (nForce590), 2GB -- 4.2.4 works fine, 4.3b6 hang loading bzroot Counting dots, it doesn't look like syslinux competes the uncompress of bzroot and it hangs in the same spot everytime. What I'm unable to determine is if the hang is in syslinux or after jumping into the early kernel init. I wish I had access to an x86 hardware debugger.

Same story for me. 4.3.b6 hangs at the same place everytime; somewhere at or near the end of loading the rootfs. No hardware changes, no BIOS changes, same USB key, reformat, re-syslinux, re-load with 4.2.4, boots to login prompt and runs fine. Repeat procedure going back to 4.3.b6? ...hang in the same place. Put 4.3.b6 USB key into ASUS A7N8X-E Deluxe, boots to login prompt.
