Bug#287690: disables DMA after ide reset
Package: kernel-source-2.6.9
Version: 2.6.9-3
Severity: normal
on a notebook I have a hardware problem which causes the harddisk
to power down for a short time. this doesn't crash the system
most of the times, but ide is resetted.
log messages:
Dec 29 16:26:14 localhost kernel: hda: status timeout: status=0x80 {
Busy }
Dec 29 16:26:14 localhost kernel:
Dec 29 16:26:14 localhost kernel: ide: failed opcode was: unknown
Dec 29 16:26:14 localhost kernel: hda: DMA disabled
Dec 29 16:26:15 localhost kernel: ide0: reset: success
DMA isn't reenabled by the reset which obviosly makes the system a lot
slower when accessing the hardware.
some information I don't think are relevant, but here it is:
- this bug is probably not version specific, I'm just using 2.6.9
instead of 2.6.8 because of a usb storage bug workaroung in 2.6.9
- disk model: TOSHIBA MK4025GAS
- IDE chipset: Intel PIIX4 Ultra 100 Chipset
