Yes, generic subject ;) After solving the problems with ICH, one other stays. One box has a VIA controller (in fact, this is a ApolloPro 266 chipset motherboard): nada:~# lspci 00:00.0 Host bridge: VIA Technologies, Inc.

The only thing hung there is the burner. When drived through standard IDE, I got this: VP_IDE: IDE controller at PCI slot 0000:00:11.1 PCI: VIA IRQ fixup for 0000:00:11.1, from 255 to 0 VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later VP_IDE: VIA vt8233 (rev 00) IDE UDMA100 controller on pci0000:00:11.1 ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:pio, hdd:pio Probing IDE interface ide0... hda: HL-DT-ST DVDRAM GSA-4040B, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hda: ATAPI 32X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache Uniform CD-ROM driver Revision: 3.20 Probing IDE interface ide1...
