SubjectSome oddity with hdparm and linux-2.5.64bk3
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.


Regards,
