Dear Penguins:
We have a problem booting vanilla 2.6.2 and 2.6.3 kernels from a USB
disk (Transcend JetFlash, both 128MB USB 2 and 256MB USB 1). During what
appears to be PCI device enumeration, we get the following panic:
kernel BUG at arch/i386/mm/ioremap.c:81!

<0>Kernel panic: Attempted to kill init!
This does not occur when booting from the hard disk, or when booting 2.4
series kernels (tried 2.4.18 through 2.4.22).
Hardware info: P4-based Intel Celeron, motherboard is SiS chipset.
We have tried to circumvent the problem by changing the kernel PCI
probing from "Any" to "BIOS" and "Direct".
The bootloader is SysLinux (1.66), using an initrd image. Kernel
parameters are set to run a serial console, but other than that, it's
just kernel and initrd.
Output from lspci (-vvv), /proc/cpuinfo and /proc/iomem from a working
2.4 kernel on the same machine is below. The kernel was compiled with
gcc 3.2.
Can anyone provide some further insight into this problem, point us in
the right direction, or let us know if this is indeed a bug?
Cheers,
Elliot Mackenzie & Doug Turk.
