Hi,
From: Igor Nekrestyanov (igor@meta.math.spbu.ru)
>I was trying 2.4.1 kernel but under some IO load (bonnie++)
Me too, same messages...
>DMA gets disabled with following messages:
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
my dmesg:
ide: Assuming 33MHz system bus speed for PIO modes
ALI15X3: IDE controller on PCI bus 00 dev 80
ALI15X3: chipset revision 195
ALI15X3: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x6050-0x6057, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0x6058-0x605f, BIOS settings: hdc:DMA, hdd:pio
hda: IBM-DJSA-210, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: 11733120 sectors (6007 MB) w/384KiB Cache, CHS=730/255/63, UDMA(33)
an other chipset but the same problem...
There are more ide_dma_timeout problems known with other chipsets.
It seems to be an chipset independent problem, it exits also in 2.4.0,
(see http://boudicca.tux.org/hypermail/linux-kernel/2001week02/1429.html)
and in 2.4.1-ac9.
Are any fixes known?
p.s.
Please cc: me explicitly, because i am not on the list.
thanks
Frank
