I have the same problem, I have tried different solutions, also mentioned here, but none of that worked. Until Feisty the kernel option ide=nodma at least removed the error messages and speed-up the boot and of course decreased hard disk performance, now withy Gutsy 7.10 this kernel parameter doesn't work anymore, messages are shown anyway and boot takes ages.
please help me Marco ** Attachment added: "dmesg" http://launchpadlibrarian.net/10155270/dmesg -- DMA timeouts on UDMA harddisks https://bugs.launchpad.net/bugs/25975 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
