Hmm... please post full uname: uname -a and hdparm device test results: hdparm -t /dev/hda It looks like a kernel problem. Did you install that 2.6.16 by hand? Or maybe you've hit the internal fragmentation level of ReiserFS v3. 83% is quite a full disc. Anyway, you have to provide cold cache timings. The dd one seems to be hot cache. # uname -a Linux host 2.6.16 #1 SMP Wed Mar 22 11:51:23 CET 2006 i686 Intel(R) Pentium(R) 4 CPU 2.60GHz GNU/Linux installed from official kernel source without patches # hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 116 MB in 3.03 seconds = 38.27 MB/sec Maybe the disk is dying? any messages about the disk in dmesg? the usual stuff in dmesg: io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered (default) Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ICH5: IDE controller at PCI slot 0000:00:1f.1 PCI: Enabling device 0000:00:1f.1 (0005 -> 0007) ACPI: PCI Interrupt 0000:00:1f.1[A] -> GSI 18 (level, low) -> IRQ 16 ICH5: chipset revision 2 ICH5: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:pio Probing IDE interface ide0... hda: IC35L120AVV207-0, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 Probing IDE interface ide1... hdc: JLMS XJ-HD166S, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 512KiB hda: 241254720 sectors (123522 MB) w/1821KiB Cache, CHS=16383/255/63, UDMA(100) hda: cache flushes supported hda: hda1 hda2 < hda5 hda6 hda7 hda8 hda9 > ReiserFS: hda9: found reiserfs format "3.6" with standard journal ReiserFS: hda9: using ordered data mode ReiserFS: hda9: journal params: device hda9, size 8192, journal first block 18, max trans len 1024, max batch 900, max commit age 30, max trans age 30 ReiserFS: hda9: checking transaction log (hda9) ReiserFS: hda9: Using r5 hash to sort names Reopen if you have some information to diagnose the problem... |
