Thanks Bart. This does solve the "nobody cared" problem. Tested-by: Frans Pop <elendil@xxxxxxxxx> I also tested it without David's initial patch (i.e. *with* IDE_HFLAG_SERIALIZE in host-flags) and that seems to work fine too: ide0 at 0x1fe02c00000-0x1fe02c00007,0x1fe02c0000a on irq 14 (serialized) ide1 at 0x1fe02c00010-0x1fe02c00017,0x1fe02c0001a on irq 14 (serialized) No idea whether serialized is to be preferred or not. Guess that's David's call now. I do still get the "bad DMA info in identify block" error for the CD drive, so that's still a regression relative to 2.6.26: hdd: host max PIO5 wanted PIO255(auto-tune) selected PIO4 -hdd: MWDMA2 mode selected +hdd: bad DMA info in identify block +hdd: host max PIO5 wanted PIO255(auto-tune) selected PIO4 Cheers, FJP -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
