I'm trying to troubleshoot a failure with my Maxtor hard drive that I have
experienced consistantly, even in the 2.2.x kernels (I'm now running
2.2.1-test10, .config is attached). It detects all of my drives fine:
block: queued sectors max/low 126786kB/95090kB, 384 slots per queue
Uniform Multi-Platform E-IDE driver Revision: 6.31
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 vt82c586b IDE UDMA33 controller on pci0:7.1
ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:DMA
hda: Maxtor 52049U4, ATA DISK drive
hdb: WDC AC31200F, ATA DISK drive
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
hdc: Maxtor 90680D4, ATA DISK drive
hdd: ATAPI 40X CDROM DRIVE, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: 40020624 sectors (20491 MB) w/2048KiB Cache, CHS=2491/255/63,
UDMA(33)
hdb: 2503872 sectors (1282 MB) w/64KiB Cache, CHS=621/64/63, DMA
hdc: 13281408 sectors (6800 MB) w/256KiB Cache, CHS=13176/16/63, UDMA(33)
hdd: ATAPI 40X CD-ROM drive, 128kB Cache, UDMA(33)
And then all the services load up, etc. Once I log in, though, either in
gdm or on the console, it will pause for around 10-15 seconds, and then
display this:
hdc: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdc: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: status timeout: status=0xd0 { Busy }
hdc: DMA disabled
hdd: DMA disabled
hdc: drive not ready for command
ide1: reset: success
(hdc is the problem, obviously) Once this occurs, the system appears to
run normally. I don't really care about hdd (cdrom), although I figure
they are probably related somehow.
Windows is able to use UDMA fine on this drive. Also note that this isn't
a UDMA66 drive, and I'm not trying to use it (most of the other posts
I've seen with similar problems were related to 66).
Drives on ide0 seem to run in udma mode just fine, also...
Here's /proc/ide/via:
----------VIA BusMastering IDE Configuration----------------

Transfer Rate: 33.0MB/s 13.2MB/s 33.0MB/s 33.0MB/s
What I don't understand is, the transfer mode still seems to be "UDMA",
but "BMDMA" is not enabled. Aren't they inter-dependant? One in the
same? I'm obviously no expert, so any help would be appreciated.
Thanks in advance,
Ryan
