Subject: [2.6.18-rc2-mm1] libata: DMA speed too slow for cdrecord
Hi...
(plz, linux-ide people, CC me, I'm subscribed to linux-kernel but not -ide, thx)
Using -rc2-mm1+libata fixes from
http://marc.theaimsgroup.com/?l=linux-kernel&m=115415195508235&w=2
(it was the same without the patch)
I get this:
werewolf:/store/tmp/burn# cdrecord dev=/dev/sr0 gno*.iso
cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.

Uh ? I have always burn at x40 with IDE. Capabilities for the burner say:
Number of supported write speeds: 6
Write speed # 0: 7056 kB/s CLV/PCAV (CD 40x, DVD 5x)
Write speed # 1: 5645 kB/s CLV/PCAV (CD 32x, DVD 4x)

Any idea ?
