RE: PROBLEM: Panic booting from USB disk in ioremap.c (line 81)

[Elliot Mackenzie]

OK, I have done that, and I recompiled an identical kernel with spinlock
support (first incarnation did not have it).

Files on syslinux USB disk include vmlinuz (2.6.3), initrd and syslinux
config.

Cheers,
Elliot.

Now we get this:
