Subject: maximum ide request size reduced with 2.5.15-git?
Date: Sat, 14 Jan 2006 20:17:11 +0100 [thread overview]
Message-ID: <43C94E37.9090909@gmx.net> (raw)
Hi,
it seems that the maximum request size for my hard drive was
reduced with one of the patches between 2.6.15 and 2.6.15-git10.
diff between 2.6.15 and 2.6.15-git10 follows:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH4: IDE controller at PCI slot 0000:00:1f.1
PCI: Enabling device 0000:00:1f.1 (0005 -> 0007)
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 5
ACPI: PCI Interrupt 0000:00:1f.1[A] -> Link [LNKC] -> GSI 5 (level, low) -> IRQ 5
ICH4: chipset revision 3
ICH4: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x1860-0x1867, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0x1868-0x186f, BIOS settings: hdc:pio, hdd:pio
Probing IDE interface ide0...
hda: SAMSUNG MP0804H, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Probing IDE interface ide1...
hdc: DV-W24ES, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
-hda: max request size: 1024KiB
+hda: max request size: 512KiB
hda: 156368016 sectors (80060 MB) w/8192KiB Cache, CHS=16383/255/63, UDMA(100)
hda: cache flushes supported
hda: hda1 hda2 < hda5 hda6 hda7 hda8 hda9 hda10 >
hdc: ATAPI 24X DVD-ROM DVD-R-RAM CD-R/RW drive, 2193kB Cache
Uniform CD-ROM driver Revision: 3.20
Will this affect performance, and if so, how can I get the old
settings back?
Regards,
Carl-Daniel
