I'll include this i= n my next patch series for amd-pstate. It's good timing because I'm overhauling= a lot of this code for 6.15. Unfortunately; your suspend failure is missing the thing I need to tell me = some important info about the failure mode(the idle mask print). This is the li= ne we should have seen printed.=20=20 https://github.com/torvalds/linux/blob/master/drivers/platform/x86/amd/pmc/= pmc.c#L733 I notice this at the top before your sequence starts though: > feb 17 22:06:52 greenstation kernel: NOHZ tick-stop error: local softirq = work > is pending, handler #08!!! And that has me most concerned that the kernel wasn't really ready for susp= end. Let's split out your s2idle suspend issue to it's own bug and try to figure out the pattern and what debug we'll need. We can keep this one for the amd-pstate issue, and I expect we can land the patch for a later 6.14-rc. --=20 You may reply to this email to add a comment.
