I've been using CD-recorders and the like with Linux for 3 years now, but
since I've upgraded to SuSE 8.1 and kernel 2.4.19 I am experiencing some
strange problems. Whenever I burn a CD (no matter which program I use), the
CPU load goes up to 100%. The CD-R buffer runs empty, but that doesn't
matter, because I've goot BurnProof. But anyway, with my SuSE 7.3 and
vanilla 2.4.17 kernel I didn't have this problem. Except with audio CDs
I've burnt. Same problem on the CD-ROM drive when reading CDs.
It is also strange that both the CD-RW and the CD-ROM appear twice in the
ide-scsi emulation. I.e. i've got sr0 and sr1 as the CD-RW, and sr2 and sr3
are the CD-ROM. Very strange. A friend of mine has got sr0 through sr7 for
his CD-RW! [With a standard SuSE 8.0 install]

Has anyone else got similar problems?

Cheers,

Arne

Have you checked to find out if your CD drive is using DMA?

# hdparm (cd device designation)

Of course I missed the obvious. :-) Thanks man. Now I've manually turned on
DMA, but hdparm is always outputting some errors -- could this be caused by
the ide-scsi emulation? Check this:

/dev/hdd:
HDIO_GET_MULTCOUNT failed: Input/output error
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
BLKRAGET failed: Input/output error
HDIO_GETGEO failed: Invalid argument

Thanks,

Arne

Those are normal "error" indications, they do not show any real problems.

Ok, I'll ignore them, then. Burning CD-Rs now works again without any major
system load. Although I still don't know why the two drives appear twice in
my system (sr0/1 and sr2/2)...
