[Qemu-devel] [PULL v2 04/11] i8259: don't abort when trying to use level sensitive irqs |

From: Hervé Poussineau <address@hidden>
This is a guest-triggerable error, as seen when using Xenix 2.3.4.
Replace hw_error by LOG_UNIMPL, so that guests can continue.
With this patch, I can install and use Xenix 2.3.4a without any problem.
I can also start installation of Xenix 2.3.4q, but it fails due to not
finding an hard disk.
