Hi
This is my basic ide setup from dmesg:
--------------------------------------------------------------- Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx PDC20268: IDE controller at PCI slot 02:0a.0 PDC20268: chipset revision 2 PDC20268: not 100% native mode: will probe irqs later ide2: BM-DMA at 0xb400-0xb407, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0xb408-0xb40f, BIOS settings: hdg:pio, hdh:pio hde: ASUS CRW-2410A, ATAPI CD/DVD-ROM drive ide2 at 0xd800-0xd807,0xd402 on irq 22 hdg: MAXTOR 6L040J2, ATA DISK drive ide3 at 0xd000-0xd007,0xb802 on irq 22 ICH2: IDE controller at PCI slot 00:1f.1 ICH2: chipset revision 4 ICH2: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xa800-0xa807, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xa808-0xa80f, BIOS settings: hdc:DMA, hdd:pio hda: ST320011A, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hdc: TOSHIBA DVD-ROM SD-M1612, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hdg: host protected area => 1 hdg: 78177792 sectors (40027 MB) w/1819KiB Cache, CHS=77557/16/63, UDMA(100) /dev/ide/host2/bus1/target0/lun0: p1 hda: host protected area => 1 hda: 39102336 sectors (20020 MB) w/2048KiB Cache, CHS=38792/16/63, UDMA(100) /dev/ide/host0/bus0/target0/lun0: p1 p2 p3 p4 ----------------------------------------------------------
I have hda on the onboard ICH2 controllers (Asus P4T533-C with i850E chipset), and hdg on a Promise TX100 controller.
If I run hdparm on the disks, I get:
---------------------------------------------------------- nosferatu root # hdparm -t /dev/hda
/dev/hda: Timing buffered disk reads: -1387 MB in 0.00 seconds = -inf kB/sec Hmm.. suspicious results: probably not enough free memory for a proper test. nosferatu root # hdparm -t /dev/hdg
/dev/hdg: Timing buffered disk reads: 64 MB in 1.61 seconds = 39.63 MB/sec nosferatu root # ----------------------------------------------------------
For the promise, all seems ok, but for the ICH2, it does not. It still worked with 2.5.59 last time I checked. Any ideas ?
PS: please CC me as I am only subscribed at work.
