Oddity booting Knoppix on Supermicro H8DMU+ board
Opterion server board, was working happily, then I tried adding a PCI-e USB 3.0 card. Would not reboot after poweron, even if the card is removed.
Goes through bios, hits grub, gets to "Loading kernel", hangs (i.e., ctrl-alt-del does not reset, requries reset or poweroff).
Reset the bios to failsafe defaults, purged nvram, no help: "Loading kernel", newline, hung.
Pulled battery did hardware reset, went into bios, loaded failsafe defaults, ditto.
I've used a unetbootin image of gentoo stage3 to boot his machine before for initial installation.
Tried that, same result: Loading Kernel, newline, hangs.
In case of hardware issue I've stripped the disk controller and drives & riser cards leaving nothing but a bare motherboard + cpu's + memory.
Same result.
Tried Knoppix via unetbootin of KNOPPIX_V7.4.2DVD-2014-09-28-EN.iso.
This is where things get wierd.
Choosing "debug64" from the main menu gives me:
loading /boot/ ... /linux64 OK
loading /boot/ ... /mininit.gz OK
early console setup
early console decompress_kernel
Bootking the Kernel
<hangs>
Choosing "knoppix64" gives slightly different:
Loading ... linux64
Loading ... minirt.gz
early console decompress
decompressing linux Parse ELF done
Booting linux kernel
<hangs>
Choosing "Default" works with:
Loading /ubnkern
Booting linux kernel
<things happen and the system ends up in window manager>
Q: Does anyone know where the documentation for ubnkern, or the differences between choosing knoppix64 or debug64 and Default are described?
Q: Anyone else with an H8DMU+ that has applied any workarounds they can share?
thanks
memtest86 does not run on the opteron

trying to run memtest86 from any of the distros leaves me back at the kernel-choice menu in ~1 sec.
