I've been wanting to try out Kubuntu and Kubuntu Mobile Phone Preview, so i've created a usb startup disk (two rather) as usual. But it doesn't boot:
These are the kernel messages I get. At the time this picture is taken (maybe half a second after it's started booting), the system is utterly locked; caps lock doesn't turn on it's light and the magic SysRq keys don't do anything.
I know there is a known bug concerning booting a 10.04 image created in 10.10, it's in the release notes, but this is a maverick image - and the bug report does look quite different from what I'm getting. I've tried it with the normal Ubuntu 10.10 Desktop image as well, just to be sure - it's the exact same error(s). Also, booting from a live CD works as expected.
The USB drive is formatted with FAT32, msdos partitioning table. USB Legacy mode is turned on in the BIOS of this machine, otherwise it won't boot from USB. I should also mention, because the error might be connected to ACPI, that I can't turn off ACPI in the bios.
