Hi,
thanks for the many tests. I planned to get to them in detail today
but it is already getting late night here ...

Looks like we have to hunt for a Sense Data defacing piece of code
in the OpenBSD kernel.
Do you know anybody who could give hints where to look ?
Are you willing to insert print statements into suspicious code and
run the modified kernel ?
Normally i would now begin to prepare a qemu VM. But it is tricky to
replay real CD hardware situations with kernels on virtual machines.
E.g. i am able to operate a real CD drive from a virtual Linux via
virtio, but the kernel does not treat the virtio device like it
would operate a real CD device. ioctl(SG_IO) does not get routed
through sr.c.
Do you have a proposal how i could lend a DVD burner of Debian 8 amd64
to a virtual OpenBSD ? (Best on plain qemu-i386 or qemu-x86_64, else on
a Debian provided VM system.)
I will look into the logs tomorrow. Maybe i find out why xorriso failed
with CD-RW where cdrecord succeeded and how exactly both fail with AHCI.
Have a nice day :)
Thomas
