[9fans] Stuck at partdisk

[Devon H. O'Dell]

Hey all,

Trying to get an updated qemu image out that we can give to SoC
students, and I'm having some issues with the installer. I seem to be
stuck at the partdisk step. The partition seems to write fine to the
disk, but when exiting fdisk, it tells me I'm not finished with
partdisk yet. Using an iso that I just downloaded today.

Ideas?

Works fine if I turn off DMA.

no need to have DMA on on qemu anyway, so you have a workaround.

Except that it's now looking to take about 5 hours to install on my 3
core AMD64 box with 8GB RAM :)

I got confused. The problem you had with dma off was in qemu or on
real hardware? Sorry.

qemu, but it hardly seems fitting given the beefiness of the machine
the emulator's running on.

It is likely a problem with the version of qemu you are
running.  On freebsd-current with qemu-0.10.1 there is no
problem with DMA (just tried with today's ISO).

You can give KVM a whirl, I have had no problems with DMA using it on a
4x4 Barcelona or an AMD64 X2.  Should notice a performance increase from
using AMD svm anyways.

Must be FreeBSD-CURRENT i386, because it sure isn't working on
FreeBSD-CURRENT amd64 with a tree I built last night :)

It's on an amd64 (3 years old, 2GB, Athlon X2).  -current as
of Mar 21, qemu & kqemu-devel were built on mar 29.  I am
using qemu, not qemu-system-x86_64 as the emulation of its 32
bit mode is not good enough.  Make sure you haven't loaded
aio.ko as async. IO is no longer necessary for kqemu.  Not
sure if 8GB is a problem but to test that you can disable
kqemu.
