Bug#640964: linux-image-3.1.0-rc4-486: BUG() triggered on XO-1 hardware
Package: linux-image-3.1.0-rc4-486
Version: 3.1.0~rc4-1~experimental.1
Severity: normal
During boot on an OLPC XO-1, I encounter the following problem. I
believe it's the statement BUG_ON(a->cpuid >= NCAPINTS*32), though I'm
not staring at an exact copy of linux-2.6 source.
Boot device: /pci/nandflash@c:\vmlinuz Arguments: ro redboot.directory=0 ubi.mtd=root root=ubi:root rootfstype=ubifs video=lxfb fbcon=font:SUN12x22 console=ttyS0,115200 console=tty0
