Re: roottask boot panic

hi,dear Adam: thanks a lot for your time and effort! You are right! But is there any difference if I build the binaries in one run or not? I still have another problem that may have the same reason as this one: If I unpack the fiasco kernel first and build it, I can run the hello(many_thread,many_tasks...) example successfully. But when I unpack the l4env and build again, the hello package can not pass the compilation processs. I can not find the reason. can you give me some advice? best wishes! >From: Adam Lackorzynski <adam(a)os.inf.tu-dresden.de> >To: l4-hackers(a)os.inf.tu-dresden.de >Subject: Re: roottask boot panic >Date: Thu6 Sep 2007 10:01:42 +0200 > > >On Wed Sep 05, 2007 at 09:47:29 +0800, huang wrote: >> I met the problem of roottask boot panic, do you know what's the reason? >> The output is: >> >> Roottask. >> Roottask boot panic: invalid KIP magic 00000001 >> [Esc] reboot, [k] kdebug, [M] memory map, [r] region map >> >> and my menu.lst is: >> title hello world >> kernel (hd0,0)/fiasco/bootstrap >> modaddr 0x02000000 >> module (hd0,0)/fiasco/fiasco -nokdb -nowait >> module (hd0,0)/fiasco/sigma0 >> module (hd0,0)/fiasco/roottask >> module (hd0,0)/fiasco/log >> module (hd0,0)/fiasco/names >> module (hd0,0)/fiasco/dm_phys >> module (hd0,0)/fiasco/names_demo > >I just tried your binaries and I don't get your panic with Qemu.
