| |
I'm having serious trouble dealing with: * 80Gb Seagate Barracuda disc (Model Number ST380011A, Firmware Revision 3.04) * on an Intel 82801AA IDE controller
It does not boot neither with 2.4.21-pre7 nor with any other tested kernel (RH-8.0 updated kernels) unless I boot with ide=nodma. With RH kernels it stalls reading the partition table. With 2.4.21-pre7 I get and error of the dma.
I've tried idebus=66, ide0=ata66 and some tweaks with hdparm to no success; each time I enabled dma the system hung.
If someone can enlighten me on how to boot with DMA enabled maybe I'd achieve a better performance than this (best result in several tries): # hdparm -tT /dev/hda /dev/hda: Timing buffer-cache reads: 128 MB in 0.85 seconds =150.66 MB/sec Timing buffered disk reads: 64 MB in 11.53 seconds = 5.55 MB/sec
These are the relevant parametres to me.
