#67378 — Bug#963689: linux-image-5.6.0-2-powerpc: stuck at 'pmac32_cpufreq' when booting

Package: src:linux
Version: 5.6.14-2
Severity: important

Dear Maintainer,
I just updated an Apple PowerBook G4 from debian 8 (latest officially
released version for powerpc) to unstable.
The latest running kernel il 3.16 while the new 5.6.0 does not boot the
machine. While booting, the last lines shown on the screen are:

pmac32_cpufreq: registering PowerMac CPU frequency driver
pamc32_cpufreq: Low: 667 MHz, High: 867 Mhz, Boot: 667 MHz

then no more lines are printed. I waited about 5 minutes before powring
off the machine. Rebooting with old kernel works.

How may I collect more information?

Bye,
Giuseppe

I just found a new kernel in sid. This new 5.7 kernel has the same
problem as the previous 5.6.0-2

#67439 — Bug#963689: How may I collect information for debugging this problem?

Hello kernel developers,
I wish to collect more information about this problem. How may I
achieve it? I tried many boot parameters but no more messages have been
printed. Is there anything I may do? Should I use specially crafted
initrd images?

Thank you,
Giuseppe

#67891 — Bug#963689: Acknowledgement (linux-image-5.6.0-2-powerpc: stuck at 'pmac32_cpufreq' when booting)

Hello,
it seems I found the problem as explained in the upstream bug I
opened[1]. Waiting for a fix, a possibile workaround proposed by kernel
developers is to unset CONFIG_VMAP_STACK.

Is it possible to change this configuration option for powerpc (32bit)
architecture?

Thank you,
Giuseppe
