Dear maintainers,

When using Snapdragon-enabled arm64 laptops, the kernel has a tendency
to freeze when performing git-heavy operations such as git fetch or git
pull.

This issue has been identified upstream and seems to be related to a
firmware issue. While the firmware is being worked on, one can apply a
patch on the hamoa.dtsi file to avoid these random crashes:

Thanks,

Hello,

Turns out the proposed patch that removes cluster_cl5 will not fix the
issue and the laptop will still crash when performing heavy git
operations.

I will let this bug open for now as it is still present, but unforward
it as the proposed patch does not work. The PR against the Debian kernel
has been closed as well.

This needs more investigation for a proper fix to be found. I will mark
it as moreinfo as well to remind myself to come back to it.

Thanks,

Agathe.
