 As noted in PR 54166, it appears the factor that triggers the frequent
 lost IDE interrutps under qemu is not the qemu version, but qemu being
 run on, built for, or built on (not sure which) NetBSD 8 rather
 than NetBSD 7.
 
 Figuring the problem might be related to new optimizations in NetBSD
 8's gcc, I tried building qemu with -O0, but that did not help; qemu
 got slower but I still got a lost interrupt (and, as a result of PR
 54166, a hang).
