Could someone please blog or write up somewhere public exactly what is going on here. This whole thing of moving /dev/hdx to /dev/sdx just silently appeared and has caused a lot off issues. Firstly some people couldn't boot or mount drives without hacking /etc/fstab (luckily most of my drives were specified using UUIDs.) Secondly the hdparm and optimising performance issue. I have a perfectly good server that I just migrated to gutsy. The IDE drives went from /dev/hda to /dev/sda. But I no longer can turn on DMA nor change it from udma2 to udma5. I am seeing a huge amount of WAIT time in the CPU waiting for disk writes and reads to complete.
Someone must know exactly what has gone on here and should comment about it. It it extremely frustrating to have major decisions made and very little communication. I can't even find out anywhere that technically says what this change was about (is it SCSI emulation or something else)? -- poor performance hard disk IDE https://bugs.launchpad.net/bugs/96693 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
