2.6.22-rc5 libata/ata_piix failure with older CDROM
I tried (again) to convert an Intel i815EP-chipset machine from IDE to libata, but libata still fails to initialise the CDROM on the machine. With 2.6.22-rc5, IDE says: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ICH2: IDE controller at PCI slot :00:1f.1 ICH2: chipset revision 5 ICH2: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA Probing IDE interface ide0... hda: IC35L080AVVA07-0, ATA DISK drive hda: selected mode 0x45 ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 Probing IDE interface ide1... hdc: CRD-8320B, ATAPI CD/DVD-ROM drive hdd: Hewlett-Packard CD-Writer Plus 9100, ATAPI CD/DVD-ROM drive hdc: selected mode 0x22 hdd: selected mode 0x42 ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 128KiB hda: 160836480 sectors (82348 MB) w/1863KiB Cache, CHS=65535/16/63, UDMA(100) hda: cache flushes supported hda: hda1 hda2 hda3 hda4 < hda5 hda6 > Switching to libata (ata_piix) results in: ata_piix :00:1f.1: version 2.11 PCI: Setting latency timer of device :00:1f.1 to 64 scsi0 : ata_piix scsi1 : ata_piix ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x0001f000 irq 14 ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x0001f008 irq 15 ata1.00: ata_hpa_resize 1: sectors = 160836480, hpa_sectors = 160836480 ata1.00: ATA-5: IC35L080AVVA07-0, VA4OA52A, max UDMA/100 ata1.00: 160836480 sectors, multi 16: LBA ata1.00: ata_hpa_resize 1: sectors = 160836480, hpa_sectors = 160836480 ata1.00: configured for UDMA/100 ata2.00: ATAPI: CRD-8320B, 1.12, max MWDMA2 ata2.01: ATAPI: Hewlett-Packard CD-Writer Plus 9100, 1.0c, max UDMA/33 ata2.00: configured for MWDMA2 ata2.01: configured for UDMA/33 scsi 0:0:0:0: Direct-Access ATA IC35L080AVVA07-0 VA4O PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 160836480 512-byte hardware sectors (82348 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 0:0:0:0: [sda] 160836480 512-byte hardware sectors (82348 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sda4 < sda5 sda6 > sd 0:0:0:0: [sda] Attached SCSI disk ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x12 data 36 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata2: port is slow to respond, please be patient (Status 0xd0) ata2: device not ready (errno=-16), forcing hardreset ata2: BUG: prereset() requested invalid reset type ata2: soft resetting port ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ata2.00: failed to IDENTIFY (I/O error, err_mask=0x1) ata2.00: revalidation failed (errno=-5) ata2: failed to recover some devices, retrying in 5 secs ata2: soft resetting port ata2.00: configured for MWDMA2 ata2.01: configured for UDMA/33 ata2: EH complete ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x12 data 36 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata2: port is slow to respond, please be patient (Status 0xd0) ata2: device not ready (errno=-16), forcing hardreset ata2: BUG: prereset() requested invalid reset type ata2: soft resetting port ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ata2.00: failed to IDENTIFY (I/O error, err_mask=0x1) ata2.00: revalidation failed (errno=-5) ata2: failed to recover some devices, retrying in 5 secs ata2: soft resetting port ata2.00: configured for MWDMA2 ata2.01: configured for UDMA/33 ata2: EH complete ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata2.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x12 data 36 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata2: port is slow to respond, please be patient (Status 0xd0) ata2: device not ready (errno=-16), forcing hardreset ata2: BUG: prereset() requested invalid reset type ata2: soft resetting port ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status 0x80 on port 0x00010177 ATA: abnormal status

Could you please check if Tejun's patch that limits ATAPI DMA to multiple of 16-bytes works: https://bugzilla.novell.com/attachment.cgi?id=147389 (The original bug is: https://bugzilla.novell.com/show_bug.cgi?id=229260#c35) -- albert - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Care to give it a shot? Confirmed, the libata ATAPI DMA changes in -rc7 fixed this issue. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
