Hi...

I'm using this plus Jeff Garzik's alloc/free cleanup patch for libata.
In my home box it works fine wrt CD-ROMs (ata-piix).

My RAID box at work has this hardware:

00:00.0 Host bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266] (rev 01)
00:01.0 PCI bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP]
00:07.0 RAID bus controller: Promise Technology, Inc. PDC20319 (FastTrak S150 TX4) (rev 02)
00:08.0 RAID bus controller: Promise Technology, Inc. PDC20319 (FastTrak S150 TX4) (rev 02)
00:0a.0 SCSI storage controller: Adaptec AIC-7892B U160/m (rev 02)
00:0b.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)
00:0c.0 RAID bus controller: Promise Technology, Inc. PDC20267 (FastTrak100/Ultra100) (rev 02)
00:0d.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 08)
00:11.0 ISA bridge: VIA Technologies, Inc. VT8233 PCI to ISA Bridge
00:11.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
00:11.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 1b)
00:11.3 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 1b)
00:11.4 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 1b)
01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x] (rev a4)

ie, a VIA PATA on-board (with just a DVD-RW), a Promise 20267 also on board
(anything hung there), an Adaptec 7892 for the system disk and 2 Promise
SATA cards for a RAID5 (software md).

I have aic driver builtin, and sata_promise and pata_via as modules.
In previous kernels I used the IDE drivers for the CD, but I have tried to
switch to libata. I looked here:

http://zeniv.linux.org.uk/~alan/IDE/STATUS.txt

and read:

VIA:
Added IRQ masking support
Completed

Now the problems. pata_via takes an eon to load:

and it does not detect the burner, as ata_piix did in my home box:

Any ideas ? There is a CDRW in ata9...
