dmesg full of i915 *ERROR* Poison interrupt

Postby hannut » 2018/03/11 08:24:48


I have a Lenovo ThinkServer TS140 connected to a Samsung smart tv with DP-to-HDMI cable.

dmesg spams contiously the below lines. systemd-journald and rsyslogd both take 25% cpu each. I have had this machine for several years and i'm not sure when this started happening. Have tried running Fedora27 and CentOS on this machine with several different kernels. All behave the same way. Now there is CentOS7 installed and tried the latest as of today stock, elrepo-ml, and elrepo-lt kernels. Google doesn't find anything exactly like this. updated bios to the latest version.

Tried to silence them with "sysctl kernel.printk=0" but didn't do anything noticeable. Also set systemd-journald setting to Storage=volatile so it wouldn't write so much to the disk.

any help would be nice :)
