--- Comment #44 from Borislav Petkov
I'm not sure if it's the same problem,
Well, "freezes at boot" is not the same as "RCU stalls".
but with kernel 4.9.0-2 I can boot fine, but after a few minutes I start getting RCU stalls. That makes processes hang and rebooting impossible (systemd shows that it's waiting for services to turn off, but never kills them, and pressing ctrl+alt+del makes it hang too). This is a desktop system with i5-3470.
Workaround is to install kernel 4.9.3 from the Kernel:stable repo.
Sounds like the fix for your issue went into 4.9.3 and you're good to go. Or what is the problem? -- You are receiving this mail because: You are on the CC list for the bug.
