Hello, I'm running a Macbook Pro first generation (Core Duo, so x86).
I ran accross these two problems while upgrading from 2.6.21-rc3 to the current git HEAD: 1. appletouch cannot initialize the device properly at boot time (the module is automatically loaded by Gentoo), I have to reload the module to get it to work. 2. ALSA hda_intel (patch_sigmatel) fails to read properly the subsystem id. "head /proc/asound/card0/codec#0" returns: > Codec: SigmaTel STAC9221 A1 > Address: 0 > Vendor Id: 0x83847680 > Subsystem Id: 0x100 > Revision Id: 0x103401 while I expect this subsystem id: 0x106b0200. This is due to a read failure in sound/pci/hda/hda_codec.c at line 553 (I have to reboot on OS X to get the id correct again, and it seems to happen quite randomly, so I'm not absolutely certain this bug is related, but it's something i have never seen before...) I found out which commit seems to cause these bugs: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d04f41e35343f1d788551fd3f753f51794f4afcf The latest GIT without this commit works fine, but doesn't with it. See below for the relevant parts of a diff, with my comments where needed, of the dmesg output with and without this commit. You can get the raw dmesg outputs, and my .config there: http://www.boichat.ch/nicolas/linux/ Best regards, Nicolas Boichat --- dmesg-2.6.21-rc4-head-notimestamp 2007-03-26 02:19:57.000000000 +0800 Vanilla git +++ dmesg-2.6.21-rc4-head-without-d04f41-notimestamp 2007-03-26 02:20:14.000000000 +0800 Vanilla git with commit d04f41e35343f1d788551fd3f753f51794f4afcf reverted. @@ -1,4 +1,4 @@ -Linux version 2.6.21-rc4 ([EMAIL PROTECTED]) (gcc version 4.1.2 (Gentoo 4.1.2)) #1 SMP PREEMPT Sun Mar 25 17:06:13 SGT 2007 +Linux version 2.6.21-rc4 ([EMAIL PROTECTED]) (gcc version 4.1.2 (Gentoo 4.1.2)) #2 SMP PREEMPT Sun Mar 25 18:16:15 SGT 2007 BIOS-provided physical RAM map: sanitize start sanitize end @@ -93,14 +93,14 @@ Enabling fast FPU save and restore... done.
