I have tried to do just that, but not succeeded (only tried with 2.6 kernels yet, compiling a 2.4.27 kernel while writing this). I have also noticed that the d-i miboot floppies for 2.6 does not work on my oldworld macs. Do you have working miboot floppies with a 2.6 kernel? If not, any clues on why miboot does not work with 2.6 kernels on floppies? -- Hans Ekbrand (http://sociologi.cjb.net) [EMAIL PROTECTED] signature.asc Description: Digital signature
Suspend
I'm running Debian/sarge on an Apple PowerBook G3 500 Mhz 'Pismo.' I've noticed that you can't suspend/hybernate/sleep the computer when you close the screen, and I was wondering if there was a solution to this, as I constantly bring my computer around with me, and booting it every time I need to put it back in my bag would be inconvenient. I know Linux typically has hybernation issues with laptops, but I was wondering if there was a solution to this. Thanks, Nathan

Questions about the new powerbook ?
Hi, I recently bought a powerbook 12 and I have installed linux on it. For the moment, I use the kernel 2.6.12rc4. It works very well but I still have 2 problems : - The suspend to disk doesn't work when X is lauched. When I try, the system blocks. Else, it works very well when X is not launched. Is it a problem with the nvidia card ? - The trackpad doesn't work. Is it planned to write a driver for this trackpad in the kernel ? Thanks

Re: Questions about the new powerbook ?
When does it exactly locks ? After unloaded modules and stop hotplug, I do echo -n disk /sys/power/state And just after that, an awful image appears and I can do nothing. When I try the keyboard, nothing happen. The unique solution is to press the power button until the Powerbook shutdown. I try the hibernate script written by the software suspend2 team, and I have the same problem.

Weird.. when you start that, it should switch back to console, that seem to be broken. Can you switch to console in general when in X ? What if you log in your machine remotely while it's in X and do chvt 1, does this work ? Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: alsa and jack latency
In order to lower the latency you first need to be able to measure it... I have been able to do some latency testing using the ALSA latencytest tools on my powerbook using 2.6.11 and some patches: [1] A patch for the genrtc kernel driver http://www.mph.eclipse.co.uk/pub/linux/patches/2.6.11/genrtc.c.patch The ioctls added can be tested using http://www.mph.eclipse.co.uk/pub/linux/patches/rtctest2.c It is important to run to this to find out the accuracy of the clock on your platform. On PPC 1024Hz is probably the highest accurate frequency. Any machine using genrtc should be able to use these ioctls, not just PPC. [2] A patch against latencytest.0.5.5 http://www.mph.eclipse.co.uk/pub/linux/patches/latencytest.patch With USE_GENERIC_TIMER selected in the makefile, this should work on any platform. For PPC I'd recommend setting USE_PPC_VEA_TIMEBASE in the Makefile. Results: Initial testing showed serious latency from the X11 tests, but the rest looks okay. [3] http://www.mph.eclipse.co.uk/pub/linux/latency/test3/index.html With a (questionable) DRM patch for the Radeon driver the results become: [4] http://www.mph.eclipse.co.uk/pub/linux/latency/test7/index.html Jack shows 11.6msec latency with -r44100 -p128 -n4. I'm working with Takashi to get [2] included. I'm not convinced [1] is needed/usefull for inclusion in the default kernel, unless I hear otherwise.

I have similar problems with snd-usb-audio and an edirol usb, which will only let jack run in oss mode. I wonder what prevents the pmac module to do so while the oss emulation layer does it very well. I am running 2.6.12-rc4, but had this problem with earlier 2.6 kernels. Any thoughts?

Re: bluetooth working on new powerbook

Works fine here, with my own kernel (a heavily patched 2.6.11.10 right now). If you want my .config send me private mail. Peculiar, but after compiling again with the Virtual HCI driver as a module and usb_core compiled as a module, the problem went away. I had to run a make-kpkg clean as well. Thanks for the info.

Backing an HFS partition
Hello, As I am trying to transfer a MacOS8.1 from a bootable hfs iomega zip disk to a bootable CD (trying to rescue a Performa630CD). I am having a hard time using mkisofs an it made me wonder: is it possible to back up an HFSPlus partition from debian? Which tools are available?

[Help request] xmule build fails for powerpc arch
Hello, I have a little problem. The building of the current xmule package fails for powerpc arch: http://buildd.debian.org/fetch.php?pkg=xmulever=1.10.0b-1arch=powerpcstamp=1116805464file=logas=raw But I have no idea, why. It seems to be a problem with the line: #include deque But as far as I understand the documentation, the line is right (package 1.9.5 successfully built for powerpc). So what do I miss? Anyone with an idea? Current sources are also available under http://allioth.debian.org/projects/pkg-xmule (see CVS).

You can't use mkisofs to make a CD that is bootable on an oldworld or nubus based mac. It isn't just a matter of having files on the CD to be able to boot from it. You need a partition map and drivers on your CD setup correctly. The zip disk would have its own partition map and drivers if it is bootable, but those drivers may not be compatible with being loaded from a CD. You might want to try burning the entire image of the zip disk (not just the HFS partition) onto a CD and see if it works. That's the only thing I can think of that might work. There isn't much free software support for bootable disks on older macs. Just reading the files from an HFS or HFS+ filesystem is easy.
