I just rebooted with my GPLPV drivers inactive (eg not hiding qemu
devices, leaving the PV network device with 'disconnected' and not
enumerating block devices), and I found that an NDIS device is using
vector 0x93, which will be the qemu realtek device. I hide it on boot,
but I forgot to hide it again after the restore which will probably be
the cause of my problems... hopefully hiding it on restore again will
stop it generating interrupts!
