Re: cdrecord floating point exception
Hi,

FreeBSD is the other operating system which
the libburnia project supports.
The bad-hald-experience reports were all
from scdbackup users on Linux of different
ages and distros. Before hald there were
other disturbing automats.

This depends on the ever changing habits
of hald when and how to probe.
I once straced one on a SuSE 9 kernel 2.6
system (i.e. an hald early version). It opened
with and without O_EXCL several times after
the tray was loaded. After some time it ended
teasing the drive.
So a good reciepe seems to be to let the
burn program load the tray and to set eventual
gracetime=0. The mishap usually happens during
the first 100 MB. But somtimes later.
Do not expect this to be deterministic.
My experiments yielded failure with about
50% of the tries.
On SuSE 10.2 it seems to be more reliably ill.
And of course, lots of media are immune:
DVD+RW, formatted DVD-RW, DVD-RAM, BD-RE.
I never saw anything fail other than CD
but did not test DVD-R[W], DVD+R, BD-R
for that.

Just naive.
Have a nice day :)
