Comment 0 for bug 1840889

Hi,

we've been running 18.04 (w/ Xubuntu) + 4.15.0-47 kernel for a while now (on Minix Z83-4 devices w/ Intel X5-Z8350 CPUs), which is working fine.

After upgrading the kernel to a newer version (> 4.15.0-47), HDMI output is not available anymore, i915 reports an invalid EDID version via dmesg I dropped the full dmesg output on Pastebin: https://pastebin.com/jXTqAzkQ

As a start I'm blaming the Linux kernel since booting 4.15.0-47 kernel works just fine.

Known faulty kernel versions are:

- 4.15.0-58-generic
- 4.15.0-59-generic
- 5.0.0-25-generic

Not sure how to best collect logs and system information for you since I'm not used to debugging black screens. However, SSH access is possible. I am happy to provide more information, if needed. We can also install and test experimental kernel versions.
