Hello everyone, I have met a problem recently after once update. My laptop suspends automatically after booting up, and suspends on and on after wakeup. I have checked up the log and there is no obvious errors. It works well on Win7 and Ubuntu Live, and on Gentoo the CPU is about 60 ℃. It also works well in single mode, but suspends quickly after I start NetworkManager service. And I found that it echo "^@" before the first-time suspend in the console.
I have tried some solutions such as pass "pcie_aspm= *force" to kernel, disable gdm service, none works. Masking suspend.target and systemd-suspend.service helps, but I want a better solution.* *Could someone help me? And what info do I need to attach?* *Simsilver*
