Hello Molle, Update: Although I did not see any hpa messages in the 2.6 log, I did see a host protected area message on hdg in the following 2.4 kernel dmesg log: SiI680: IDE controller at PCI slot 00:0b.0 PCI: Found IRQ 4 for device 00:0b.0 SiI680: chipset revision 2 SiI680: not 100% native mode: will probe irqs later SiI680: BASE CLOCK == 133 ide2: MMIO-DMA , BIOS settings: hde:pio, hdf:pio ide3: MMIO-DMA , BIOS settings: hdg:pio, hdh:pio hdc: CREATIVECD-RW RW6424E, ATAPI CD/DVD-ROM drive hde: FUJITSU MPA3035ATU, ATA DISK drive hdf: IBM-DAQA-33240, ATA DISK drive blk: queue c031fc68, I/O limit 4095Mb (mask 0xffffffff) blk: queue c031fda4, I/O limit 4095Mb (mask 0xffffffff) hdg: WDC AC23200L, ATA DISK drive blk: queue c03200bc, I/O limit 4095Mb (mask 0xffffffff) ide1 at 0x170-0x177,0x376 on irq 15 ide2 at 0xd080d080-0xd080d087,0xd080d08a on irq 4 ide3 at 0xd080d0c0-0xd080d0c7,0xd080d0ca on irq 4 hde: attached ide-disk driver. hde: 6835952 sectors (3500 MB), CHS=6781/16/63, UDMA(33) hdf: attached ide-disk driver. hdf: 6346368 sectors (3249 MB) w/96KiB Cache, CHS=6296/16/63, DMA hdg: attached ide-disk driver. hdg: host protected area => 1 hdg: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } hdg: task_no_data_intr: error=0x04 { DriveStatusError } hdg: 6346368 sectors (3249 MB) w/256KiB Cache, CHS=6296/16/63, UDMA(33) Partition check: hde: [PTBL] [425/255/63] hde1 hdf: [PTBL] [395/255/63] hdf1 hdg: [PTBL] [395/255/63] hdg1 ide: late registration of driver. ----------- Also the partition check message doesn't appear in the 2.6 log either. Here is the 2.6 log: SiI680: IDE controller at PCI slot 0000:00:0b.0 ACPI: PCI Interrupt 0000:00:0b.0[A] -> GSI 17 (level, low) -> IRQ 177 SiI680: chipset revision 2 SiI680: BASE CLOCK == 133 SiI680: 100% native mode on irq 177 ide2: MMIO-DMA , BIOS settings: hde:pio, hdf:pio ide3: MMIO-DMA , BIOS settings: hdg:pio, hdh:pio Probing IDE interface ide2... hde: FUJITSU MPA3035ATU, ATA DISK drive hdf: IBM-DAQA-33240, ATA DISK drive ide2 at 0xd081a080-0xd081a087,0xd081a08a on irq 177 Probing IDE interface ide3... hdg: WDC AC23200L, ATA DISK drive ide3 at 0xd081a0c0-0xd081a0c7,0xd081a0ca on irq 177 Probing IDE interface ide0... hde: max request size: 64KiB hde: 6835952 sectors (3500 MB), CHS=6781/16/63, UDMA(33) hde: cache flushes not supported hde: hde1 hdf: max request size: 64KiB hdf: 6346368 sectors (3249 MB) w/96KiB Cache, CHS=6296/16/63, DMA hdf: cache flushes not supported hdf: hdf1 hdg: max request size: 64KiB hdg: 6346368 sectors (3249 MB) w/256KiB Cache, CHS=6296/16/63, UDMA(33) hdg: cache flushes not supported hdg: hdg1 ----------- The irq 177 for the card is due to the 2.6 kernel being smp and using apic. The 2.4 kernel isn't an smp kernel. Also there is some question of the drive geometry between the different kernels. The hdparm -g outputs differ. Apparently the parition check is setting lba geometry. I need to recompile hdparm on each kernel to verify this though. ----- Original Message ----- From: "James Olson" <big_spender12@xxxxxxxxx> To: "ATARAID (eg, Promise Fasttrak, Highpoint 370) related discussions" <ataraid-list@xxxxxxxxxx> Subject: Re: Fw: medley raid problem Date: Fri, 28 Oct 2005 12:48:05 -0500 > > > ----- Original Message ----- > From: "Molle Bestefich" <molle.bestefich@xxxxxxxxx> > To: "ATARAID (eg, Promise Fasttrak, Highpoint 370) related discussions" > <ataraid-list@xxxxxxxxxx> > Subject: Re: Fw: medley raid problem > Date: Fri, 28 Oct 2005 06:35:23 +0000 > > > > > James Olson <big_spender12@xxxxxxxxx> wrote: > > > Also I tried this exact same hardware setup using Redhat 9 with a 2.4.32-rc1 kernel, > > > loading modules ataraid and medley.
