---------------------+------------------------------
Running recent nightlies in QEMU/KVM hangs the mouse and causes one cpu
core to run 100%.
KDL show Ipro driver processing around 1 million ints at point when
installer shows up. All problems go away if I disable USB in QEMU launch
args.
KDL Ints output:
{{{
int 11, enabled 2, handled 720013, unhandled 0
ipro1000:iflib_fast_intr_ctx (0xffffffff85c33340), data
0xffffffff829ed098, handled 720006
uhci:_ZN4UHCI16InterruptHandlerEPv (0xffffffff81f52a10), data

}}}
QEMU/KVM command line:
