RE: problem when booting Linux With Wedge

Using a VM of size 100Meg and a wedge size of 64M won't leave too much
memory to the guest. Try increasing the VM size. With respect to the
exception: maybe something's wrong with your linux installation on the hard
disk? Do you have a installation with TLS libs? Try renaming /lib/tls to
/lib/tls.disabled (likewise /usr/lib/tls, if existing), and boot again.
Alternatively, you can try the ramdisk provided under
http://l4ka.org/download/tools/linux-ramdisk.img.gz. If you execute "make
run-qemu" the build script will download the image automatically and execute
the guest in qemu with the ramdisk. If nothing helps, inspect the guest code
at that lead to the "VCPU0 Unsupported exception from user-level ip 77e6af3a
TID 40e8001". You can do so by using the L4 kernel debugger to disassemble
the address space of TID 40e8001 at that address.
