dmesg output for v5.3-rc6 mainline kernel
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. I had
opened an issue at Ubuntu, but was told to report this upstream (reference:
<a href="https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1840889">https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1840889</a>)
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: <a href="https://pastebin.com/jXTqAzkQ">https://pastebin.com/jXTqAzkQ</a> (with
4.15.0-58-generic). Attachment contains dmesg output of mainline kernel
v5.3-rc6
As a start I'm blaming the Linux kernel / i915 since booting 4.15.0-47 kernel
works just fine.
Known faulty kernel versions are:
- Ubuntu Kernel: 4.15.0-58-generic
- Ubuntu Kernel: 4.15.0-59-generic
- Ubuntu Kernel: 5.0.0-25-generic
- Mainline Kernel: v5.3-rc6
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.
Note: This happens then attached via a standard HDMI cable as well as with a
HDMI-DVI cable on different monitor setups.</pre>
