Hi L4 hackers,

 > and it built ok. Now when it runs fbdrv page faults. Has anyone seen 
this before?

The same story: page fault https://pbs.twimg.com/media/DBPuT-sUMAAuhvU.png

I svn co all pkgs, and mkiso like this:

make grub2iso E=framebuffer-example-x86 
MODULE_SEARCH_PATH=/home/zhaixiang/project/l4re/kernel/fiasco/build:/home/zhaixiang/project/l4re/l4/conf/examples:/home/zhaixiang/project/l4re/l4/pkg/io/io/config

then run by qemu:

make qemu E=framebuffer-example-x86 
MODULE_SEARCH_PATH=/home/zhaixiang/project/l4re/kernel/fiasco/build:/home/zhaixiang/project/l4re/l4/conf/examples:/home/zhaixiang/project/l4re/l4/pkg/io/io/config

equals to:

qemu-system-x86_64 -kernel 
/home/zhaixiang/project/l4re/l4/build/bin/amd64_K8/bootstrap -append 
"bootstrap -modaddr 0x01100000" -initrd

,/home/zhaixiang/project/l4re/l4/build/bin/amd64_K8/l4f/ex_fb_spectrum_cc "

and I even changed x86-legacy.devs

    RTC = Hw.Device(function()


but it doesn't help, what did I miss? please give me some advice, thanks 
a lot!
