Hi all, I get kernel panic on 'floppy' module load. If I blacklist the module, then everything works. The issue happens in Xen HVM, other virtualization modes (PV, PVH) works fine. PV dom0 works too. I haven't tried bare metal, but I assume it works fine too.
Could you please try bare metal? Working in PV and PVH mode, but not in HVM, is pointing towards either an issue in IRQ handling (not Xen specific) or in qemu. It might be that Xen is advertising a rarely used APIC mode. In case bare metal is working it might be helpful to have APIC related boot message differences between HVM guest and bare metal. Juergen
