Not much actually - perhaps I need to enable some debugging: Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx hdc: SanDisk SDCFX-4096, CFA DISK drive ide1 at 0x170-0x177,0x376 on irq 15 hdc: max request size: 128KiB hdc: 8027712 sectors (4110 MB) w/1KiB Cache, CHS=7964/16/63 hdc: hdc1 hdc2 hdc3 > > --- [2] > > ata2.00: limiting speed to UDMA/33:PIO4 > > ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen > > ata2.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 cdb 0x0 data 4096 in > > res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) > > ata2: soft resetting port > > ata2.00: configured for UDMA/33 > > ata2: EH complete > > What happens after this? More EH occurs - I've left it for ~5 mins, but let me know if longer would give more information, eg if it converges on a lower speed. Would it be useful to compare some of the port setup registers in the working and non-working cases? Or any other debug I can grab? -- Daniel J Blueman
