When the system boots the kernel no longer recognises the partition tables of two of my hard drives. Using the same config anything below 2.6.6 works flawlessly but all the newer versions give this same error. Both drives are identical, have two primary partitions and are on the secondary IDE bus. I have tried enabling advanced partition selection in the kernel config as well as ide stroke but neither did help. Dmesg gives the following output: PIIX4: IDE controller at PCI slot 0000:00:07.1 PIIX4: chipset revision 1 PIIX4: 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: Maxtor 6Y160P0, ATA DISK drive hdb: CD-W512EB, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 Probing IDE interface ide1... hdc: IC35L090AVV207-0, ATA DISK drive hdd: IC35L090AVV207-0, ATA DISK drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 1024KiB hda: 320173056 sectors (163928 MB) w/7936KiB Cache, CHS=19929/255/63, UDMA(33) hda: cache flushes supported /dev/ide/host0/bus0/target0/lun0: p1 p2 p3 p4 hdc: max request size: 1024KiB hdc: 160836480 sectors (82348 MB) w/1821KiB Cache, CHS=16383/255/63, UDMA(33) hdc: cache flushes supported /dev/ide/host0/bus1/target0/lun0: unknown partition table hdd: max request size: 1024KiB hdd: 160836480 sectors (82348 MB) w/1821KiB Cache, CHS=16383/255/63, UDMA(33) hdd: cache flushes supported /dev/ide/host0/bus1/target1/lun0: unknown partition table hdb: ATAPI 32X CD-ROM CD-R/RW drive, 2976kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.20 For reference here is the output of the working 2.6.6 kernel: PIIX4: IDE controller at PCI slot 0000:00:07.1 PIIX4: chipset revision 1 PIIX4: 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 hda: Maxtor 6Y160P0, ATA DISK drive hdb: CD-W512EB, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hdc: IC35L090AVV207-0, ATA DISK drive hdd: IC35L090AVV207-0, ATA DISK drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 1024KiB hda: 320173056 sectors (163928 MB) w/7936KiB Cache, CHS=19929/255/63, UDMA(33) /dev/ide/host0/bus0/target0/lun0: p1 p2 p3 p4 hdc: max request size: 1024KiB hdc: 160836480 sectors (82348 MB) w/1821KiB Cache, CHS=16383/255/63, UDMA(33) /dev/ide/host0/bus1/target0/lun0: p1 p2 hdd: max request size: 1024KiB hdd: 160836480 sectors (82348 MB) w/1821KiB Cache, CHS=16383/255/63, UDMA(33) /dev/ide/host0/bus1/target1/lun0: p1 p2 hdb: ATAPI 32X CD-ROM CD-R/RW drive, 2976kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.20 Thank you very much for any help you can give.
