 There is now also a corresponding qemu bug ticket:
 
   https://bugs.launchpad.net/bugs/897771
 
 The comments in that ticket identify the exact qemu commit that
 triggered the regression, but it's not clear to me from the diffs how
 that commit broke interoperability with NetBSD.
 
 On the NetBSD side, all versions newer than CVS date
 2011.02.10.00.43.20 are effected; the commit message for the commit in
 case says "Reinstate INSTALL kernel for embedded ramdisk installs".
 I assume the reason earlier versions are not affected is that their
 installation kernels do not support ACPI.
 
 In any case, it would be useful to fix both NetBSD and qemu: NetBSD
 should be fixed so that future versions of NetBSD will run under
 today's qemu, and qemu should be fixed so that future version of qemu
 will run today's version of NetBSD.
 
 I have also obtained a more detailed stack trace by attaching a
 remote gdb to qemu's built-in gdb server; the relevant parts
 read as follows:
