 asic in suspend (v2)") on suspend?

My problem has never been fixed. The proposed patch has been applied to 5.15. I do not remerber which version 28 maybe.

I still have à RIP in pm_suspend. Did not test the Last two 15 versions.

I can leave with 5.10 est using own compiled kernels.

Thanks for asking.
