i have a mysterious double fault error while booting fiasco in qemu.
the problem is that the same configuration works on a native 586 fiasco
and in fiasco-ux without any problems. only with qemu a double fault is
i tested it with qemu 0.9.0 and qemu 0.9.1. with version 0.9.0 the boot
process hangs, without any error messages. with qemu 0.9.1 fiasco says
that a double fault was detected.
in my configuration i boot two instances of l4linux. while the
intialization of the
l4linux kernel, fiasco produces the following output:
EAX=c02407d0 ESI=c0240000 DS=0023
EBX=c0401000 EDI=00000000 ES=0023
ECX=3fe19000 EBP=c02406b4 GS=0043
EDX=00000000 ESP=c04017cc SS=0010 ESP0=c0240800
EFL=00200087 EIP=f002ef06 CS=0008
this happens always after the "l4lx | Got 0 out of 65536 I/O ports"
message. but the really
confusing thing is, that sometimes also qemu can boot without any double
any ideas whats going wrong here?
