[Bug 96692] Re: ata_piix used instead of AHCI for Mac Pro
I am having the same issue on my macbook. 9.04 beta is using the ata_piix driver instead of the AHCI driver. As others mentioned earlier in this thread, the problem seems to be that the Apple bios emulator puts the controler into legacy mode (for which the ata_piix probably is the correct driver). ( http://forum.onmac.net/showthread.php?t=2739 has a reasonable summery of the problem and a solution). In a previous install of ubuntu, I had tried the fix using the modified stage1 grub and it worked perfectly fine. However, I would rather not install code into my MBR from a random untrusted webpage again and thus I would prefer, If ubuntu could provide a correctly patched stage1 for grub that reenables the AHCI mode on the MacBook. It is also necessary to make sure that you have the correct one (either RAID version or the AHCI version) and I wasn't sure which version the ones found on the various websites are. Would it be possible for Ubuntu to provide this modified grub and perhaps add some comments about this issue on the documentation pages for running Ubuntu on a intel mac? -- ata_piix used instead of AHCI for Mac Pro https://bugs.launchpad.net/bugs/96692 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 96692] Re: ata_piix used instead of AHCI for Mac Pro
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel.

[Bug 96692] Re: ata_piix used instead of AHCI for Mac Pro
Same problem/bug/feature found on Supermicro's X7DBE+ motherboard: the Intel ESB2 IDE+SATA controller gets the ata_piix driver instead of the ahci driver under Fiesty (Ubuntu kernel 2.6.20-15-generic). On top of making the IDE controller flaky, this removes 1/3 of the SATA controller: the ata_piix dirver recognizes only 4 SATA drives instead of 6. :( :( Here are the two salient lines of the lspci -vvnn report: IDE interface [0101]: Intel Corporation 631xESB/632xESB IDE Controller [8086:269e] (rev 09) (prog-if 8f [Master SecP SecO PriP PriO]) IDE interface [0101]: Intel Corporation 631xESB/632xESB/3100 Chipset SATA Storage Controller IDE [8086:2680] (rev 09) (prog-if 8f [Master SecP SecO PriP PriO]) Exactly the same problem as reported by Shaw hereabove. I work with a small ISP in Canada, where we use this Supermicro motherboard in our servers, with two dual-core Xeon 5150 apiece. Losing 2 of our 6 SATA drive is as real problem as having our servers running way too slow. (We are using KVM + kqemu in these servers.)

[Bug 96692] Re: ata_piix used instead of AHCI for Mac Pro
New Intel IDs aren't being added to ahci because ahci controllers have their own PCI class ID (0x010601) which ahci can key off. Apple seem to have declined to program yours as an ahci device - it's still claiming to be an IDE device (0x0101), and so ata_piix is the correct driver to be using. Of course, this ignores the fact that in reality we'd prefer to use ahci. The easiest way to do this would probably be to add a PCI quirk that reprograms it, but Apple seem to have declined to provide an Apple subsystem ID to key off and argh it hurts. -- ata_piix used instead of AHCI for Mac Pro https://launchpad.net/bugs/96692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
