I own IBM's 61gb IC35L060AVER07-0 drive. ABIT KG7-RAID with HPT370 First I have been running "Linux version 2.4.2-2" RH7.1 and this sets the above setup to ATA-100 and I had not experienced any problems. Once I "upgraded" to 2.4.10 my drive got blacklisted and runs as ata-44. to double check, I removed the driver from blacklist for 100 and 66 and recompiled kernel, and it seems to be running fine so far. now there's weird part, for both drive running at ATA-44 and ATA-100 I get pretty much same numbers from hdparam. Perhaps it just an change to printf alone, and drive runs at ata-100 even it if says that it is ata-44 ? what kind of numbers should I expect from ATA-100 drive anyway? hde: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63, UDMA(44) dev/hde: Timing buffer-cache reads: 128 MB in 0.70 seconds =182.86 MB/sec Timing buffered disk reads: 64 MB in 1.68 seconds = 38.10 MB/sec hde: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63, UDMA(100) /dev/hde: Timing buffer-cache reads: 128 MB in 0.68 seconds =188.24 MB/sec Timing buffered disk reads: 64 MB in 1.69 seconds = 37.87 MB/sec --------------------------------------- ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller on PCI bus 00 dev 39 VP_IDE: chipset revision 6 VP_IDE: not 100% native mode: will probe irqs later VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1 ide0: BM-DMA at 0xc400-0xc407, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xc408-0xc40f, BIOS settings: hdc:DMA, hdd:DMA HPT370A: IDE controller on PCI bus 00 dev 98 PCI: Found IRQ 11 for device 00:13.0 PCI: Sharing IRQ 11 with 00:09.0 HPT370A: chipset revision 4 HPT370A: not 100% native mode: will probe irqs later ide2: BM-DMA at 0xe800-0xe807, BIOS settings: hde:DMA, hdf:pio ide3: BM-DMA at 0xe808-0xe80f, BIOS settings: hdg:pio, hdh:pio hda: WDC WD272AA, ATA DISK drive hdc: QPS CD-R PX-W8432T, ATAPI CD/DVD-ROM drive hdd: LG DVD-ROM DRD-8120B, ATAPI CD/DVD-ROM drive hde: IC35L060AVER07-0, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 ide2 at 0xd800-0xd807,0xdc02 on irq 11 hda: 53128656 sectors (27202 MB) w/2048KiB Cache, CHS=3307/255/63, UDMA(66) hde: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=119150/16/63, UDMA(100) -- Adam http://www.eax.com The Supreme Headquarters of the 32 bit registers - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
