Subject: x86/amd_nb: Check for invalid SMN reads
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/patch/?id=3...
This commit is breaking lid close system suspend and opening won't bring the laptop back and no input is possible anymore here. I have to hard reboot the laptop. It's a Lenovo Thinkpad T14 Gen1. There's nothing in the journal.
Reverting this commit on top of 6.6.35 allows proper suspend/resume again.
Thanks Andy for the report.
Mario, Any ideas? Maybe something with the platform drivers?
Thanks, Yazen
Interesting; I've tested this patch in my own tree for a few weeks now and never hit this.
Can you please share a dmesg log from bootup? Is there an "error reading" message from amd-pmc?
Separately can you please add a debug statement to amd-pmc around the two calls for: err = amd_smn_read(0, AMD_PMC_BASE_ADDR_LO, &val); err = amd_smn_read(0, AMD_PMC_BASE_ADDR_HI, &val);
Both with and without the patch? I'm guessing one of them is (~0ULL) which is exactly what this patch is actually looking for now.
