Dear maintainers, I kept Bug#927324 machine "Stretch -> dist-upgraded Buster".
I re-connected the LCD and the machines via the HDMI switch. * Different machine, same HDMI switch, same LCD. Bug#927324 machine status ========================= I reported unstable HDMI LOS issue after resume. I tested again after the upgrades. * s2ram from root tty works. * suspend from GNOME, works. * suspend by Power button, works. * though, sometimes, it fails LCD back, * AND, i2c NAK bailout log are in syslog. My observation -------------- Compared with that machine, this report's machine (H110 Skylake) shows more HDMI LOS reproductivity; almost 100%, both Stretch tty and Buster tty. So it might be an usual combination problem of hardware. Especially, the motherboards differ. Regards.
