Re: Powermac g5 strange colors with gui

[Peter Saisanas <psaisanas@gmail.com>]

Hi Aidan & Rick,

Aiden:    Regarding the Powermac G5 AGP (7.2) it seemed like the PMU option was required for your machine. So we are making progress!
Unfortunately, it seems that i didn't include the windfarm_pm72 driver in the kernel build.
I have corrected that in a new 4.4.0-rc7 rev2 test kernel deb package.

Rick:    In the previous 4.4.0-rc7 kernel build, i had the MD RAID driver was compiled as a module. However i have altered the kernel config and built it in the kernel monolith. Doing it this way also apparently enables the kernel to autodetect the raid array. Perhaps before it didn't load the MD module automatically and thats why it wouldn't mount your lvm2 root volume.... Just a guess. Hopefully i'm right?
I have changed the config in a new 4.4.0-rc7 rev2 test kernel deb package. Fingers crossed!

Haven't played around with a Powermac G5 (7.2) or lvm on linux before.

Thanks for the feedback.

Same deal as before, google drive link below, in the 4.4.0-rc7 folder the kernel has been rebuilt to rev2. Please provide full dmesg logs (just a reminder, i know you guys already do that if possible) :)

Good luck & thanks for trying these test kernel deb packages out.

Best Regards,
Peter

Hello,

The kernel works for me. I'm emailing you from the computer now. The fans unfortunately persist in their loudness, but the kernel is booting. I've attached the output of dmesg with this email.

Thanks!

Aidan

I tried the new 4.4.0-r7 kernel.  Sadly, it failed to boot.  Jpg of screen attached.  It’s a little blurry.  Incase you have trouble reading it, the last few lines of text say:

rtc-generic rtc-generic: setting system clock to 2016-01-03 …
List of all partitions:
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 4.4.0-rc7-powerpc64 #1
Call Trace:
   …
Rebooting in 180 seconds..

In preparation, I did
    dpkg -i linux-headers-4.4.0-rc5-powerpc64_1_powerpc.deb
    dpkg -i linux-headers-4.3.0-powerpc64_1_powerpc.deb
    update-initramfs -u
    ybin -v

I already had made an entry in /etc/yaboot.conf that loads the appropriate kernel and initramfs

The root filesystem is on an LVM2 partition on a RAID1 array
