Script done on Wed Jun 14 17:10:17 2006
ktrace shows burncd getting EIO on its first write to /dev/acd0.
>How-To-Repeat:
See above script.
>Fix:
If a CD has a TOC, the acd driver reports the CD's current size to
GEOM, and GEOM later prevents writes beyond the last session on the
media. Writing the first session works because the driver sets the
disk size to (u_int32_t)-1, which gets cast to an int64 for GEOM,
becoming 0xffffffff.
This patch sets the media size for GEOM to a large positive number,
but only when the device is opened writable.
