I'm running:

localhost(6.1-P)[21] uname -a
FreeBSD localhost 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #19: Wed Mar 15 07:15:25 PST 2006     root@g1-18.catwhisker.org.:/common/S2/obj/usr/src/sys/LAPTOP_30W  i386
localhost(6.1-P)[22] 

I figured I'd grab a copy of the recent 6.1-BETA4 (disc1) ISO to
try it out & hand it out to folks....

It seems to have worked, but I got a bit of a whine in the "fixate"
stage:

I've used CDs from this batch successfully before -- they're TDK 650 MB
media; it's not as if the ISO image is too big for the media.

I certainly don't recall this behavior with 4-STABLE; my recent
migration to 6-STABLE was a bit precipitous (though I had been
tracking 6-STABLE, it was on a slice I didn't really use all that
much on my laptop).

I just tried it again, using a different brand of media, and also got:

localhost(6.1-P)[22] sudo burncd -s max -f /dev/acd0 data 6.1-BETA4-i386-disc1.iso fixate

fixating CD, please wait..
burncd: ioctl(CDRIOCFIXATE): Input/output error
localhost(6.1-P)[23] 

There was a fair amount of time -- around 15 - 20 seconds -- between the
"fixating CD, please wait.." message and the whine, during which there
was activity involving the CD drive.

Am I doing something stupid here?

If not, it would be nice to not get this kind of behavior once 6.1 is
released.

Thanks...!

Peace,
david
