loading linux-3.3 with ski sim crashes

i'm using gcc-4.5.3, binutils-2.22, and linux-3.3. i did make sim_defconfig, then make, then make boot.

now i'm trying to load it up into ski, but it crashes. any ideas ?

$ ski linux-3.3/bootloader linux-3.3/vmlinux root=/dev/sda simscsi=images/sda
run

Al Viro got SKI to boot just over a week ago. The only problem that he reported was this one:

http://www.spinics.net/lists/linux-scsi/msg59106.html

Your stack trace doesn't look all that likely to match this (no scsi anything in your trace) ... but worth trying either Al's patch or jejb's proposed better patch.

-Tony

i tried linux-3.4-rc7 instead and doesn't oops on boot. it hits scsi errors (not oops), but this looks like something i can poke further. -mike

ok, those failings were due to incorrect use of simscsi and poor documentation. fortunately, strace helped, and i'm booting userland now.

i didn't need that patch to boot, but it didn't hurt either. -mike
