Hi, Multiple Qubes users have reported issues with resuming from S3 on AMD systems (Ryzen 2500U, Ryzen Pro 3700U, maybe more). The error message is:
(XEN) CPU0: cap[ 1] is 7ed8320b (expected f6d8320b) If I read it right, this is: - OSXSAVE: 0 -> 1 - HYPERVISOR: 1 -> 0 Commenting out the panic on a failed recheck_cpu_features() in power.c makes the system work after resume, reportedly stable. But that doesn't sounds like a good idea generally. Is this difference a Xen fault (some missing MSR / other register restore on resume)? Or BIOS vendor / AMD, that could be worked around in Xen? -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?
