Um yes it is.
How could I otherwise have booted far enough to get the panic?
My boot partition is on the usb I cant boot from hard drive.

Is USB even an option to boot off of in the BIOS? How could the OS boot to
something that isn't detected in the bios? IMHO.

Subject: Booting from USB with initrd

Hi Im trying to boot an encrypted file system using an initrd on a USB.
I use syslinux for the actual boot process as I couldnt get Grub to boot
of it for some reason. This is the .cfg

default vmlinuz
timeout 100
prompt 1
label linux
kernel vmlinuz
append initrd=/initrd.gz root=/dev/ram0 rootfstype=minix init=/linuxrc

As far as I can tell this should load the initrd but that never happens.
Everything seems to boot fine. Syslinux loads the kernel and I get to
the point where initrd should be mounted only to get this error.

Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(1,0)
followed by the USB information and stop.
<5> Vendor SWISSBIT Mode: Victorinox 2.0 Rev 2.00
Type Direct-Access ANSI SCSI Revision: 02
SCSI device sdb: 1022720 512 byte hdwr sectors (524mb)
sdb: Write Protect is off
sdb: asuming driver cache: write-through

I have support for minix, vfat, ext2 and ext3 in the kernel. I have
recompiled the
kernel
like 20 times to test different things. So what Im thinking is that the
USB device doesn't
get realized before syslinux tries to load it?

Oh I do have the ramdisk in the kernel and everything.
