Hi,
I have the same symptom, but with plugging and unplugging a monitor and =
also just toggling the monitor's power.
With the high interrupt happening I did your dmesg test. I got a whole =
bunch of :
xhci_interrupt: real interrupt (sts=3D0x00000000, iman=3D0x00000002)
I have seen this on a :
Gigabyte GA-Z77-DS3H (with Core i3-2120T)
Intel DH77KC (same Core i3-2120T)
I'm using the intergrated graphics on the cpu.
It doesn't matter whether the DSUB (only on the GA) or DVI port is used.
Currently I'm on the Intel board and its interrupt usage reported by =
systat -vmstat is :
