Hello
all,
Having some trouble setting up my new CMD649 based UDMA 100 ATA controller under Linux. Every time DMA is enabled a kernel error message like this is displayed: hde: timeout waiting for DMA ide_dmaproc: chipset supported ide_dma_timeout func only: 14 hde: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest } hde: DMA disabled I've altered the hardware configuration/cables etc and tried a few patch levels with the latest being TEST9-PRE9. Same type of errors with all configurations. The help screen for CMD64X in the kernel configurator doesn't even include CMD649 (only CMD648 for example) so maybe this thing is too new for Linux support? Anyway, I'd be happy to test any and all patches sent my way...... =======================[Boot Messages]============================ Linux version 2.4.0-test9 (root@mach110) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Mon Oct 2 20:54:20 EDT 2000 BIOS-provided physical RAM map: BIOS-e820: 000000000009fc00 @ 0000000000000000 (usable) BIOS-e820: 0000000000000400 @ 000000000009fc00 (reserved) BIOS-e820: 0000000000010000 @ 00000000000f0000 (reserved) BIOS-e820: 0000000000010000 @ 00000000ffff0000 (reserved) BIOS-e820: 0000000009f00000 @ 0000000000100000 (usable) On node 0 totalpages: 40960 zone(0): 4096 pages. zone(1): 36864 pages. zone(2): 0 pages.
