Hi, I'm having problems with my disk on a Latitude D820 after upgrading kernel to any >2.6.20 No DMA support can be activated, giving me a very poor I/O performance. I'm using ata_piix driver on a ICH7 system with no AHCI support AFAIK I opened a thread[1] on gentoo-forums (the distro I use) with all the output i think can be interesting. Hope you can help me guys. Thanks for all :) [1] http://forums.gentoo.org/viewtopic-p-4731161.html -- Mikel Olasagasti <hey_neken@xxxxxxxxxxxx> - 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
