https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270489 --- Comment #7 from Lu=C3=ADs Henriques <henrix@camandro.org> --- I don't really know what's happening at the low-level here in this patch, b= ut I've done some blind testing here's what I learned: the system wakes up from suspend if I comment the following lines from the patch: ... identify_cpu_ext_features(); hw_ibrs_recalculate(true); /* * hw_ssb_recalculate(true); * amd64_syscall_ret_flush_l1d_recalc(); * x86_rngds_mitg_recalculate(true); */ mca_resume(); if (vmm_resume_p !=3D NULL) vmm_resume_p(); ... If I uncomment the next line (hw_ssb_recalculate(true)) the laptop won't wakeup. But as I said, I've no idea why, this was just blind testing. --=20 You are receiving this mail because: You are the assignee for the bug.=
