Subject: DOS VM problem with QEMU-KVM and newer kernels
Date: Thu, 12 Apr 2012 20:32:22 +0200 [thread overview]
Message-ID: <4F871FB6.4020906@wiesinger.com> (raw)
Hello,
I'm having problems with recents kernels and qemu-kvm with a DOS VM:
TD286
System: Bad selector: 0007
System: Bad selector: 0D87
System: Bad selector: 001F
System: Bad selector: 0007
GP at 0020 21D4 EC 0DC4
Error 269 loading D:\BP\BIN\TD286.EXE into extended memory
Another 286 DOS Extender application also rises a general protection fault:
GP at 0020 18A1 CODE 357C
Doesn't depend on the used DOS memory manager and is always reproduceable.
Depends only on kernel version and not qemu-kvm and seabios (tried to
bisect it without success):

CPU is an AMD one.
Any ideas how to fix it again?
Any switches which might help?
Thnx.
Ciao,
Gerhard
