[Qemu-devel] QEMU FreeBSD 6.1 "npxdna: fpcurthread == curthread" spewage

[Zach Metzinger]

Hi-

I'm using qemu-0.8.1 under FreeBSD 6.1-RELEASE from ports with
kqemu-1.3.0pre7 (also from ports). The guest OS is Windows XP SP2.
When I use the -kernel-kqemu flag to qemu, I get the following kernel
console messages:

Jun 21 14:04:57 jitter kernel: npxdna: fpcurthread == curthread 5173 times
Jun 21 14:04:57 jitter kernel: npxdna: fpcurthread == curthread 5174 times
<...>

This happens quite a bit (5-10 a second) when using any block device.
I assume this is because kernel I/O calls are being virtualized and
are the cause of this.

When I do not use -kernel-kqemu, I do not get these messages. In both
cases, Windows appears to work fine.

This thread:

appears to have some information on why this happens. Has a patch been
released to fix this bug?
