September 24, 20223 yr This is one of a handful of challenges I'm facing since upgrading from 6.10.3 to 6.11. I'm starting with what I hope is low hanging fruit. Since upgrading, my log is flooded with "kernel: EDID block 0 is all zeroes" I have a supermicro X11SSH-F motherboard with an e3-1285v6. I hardware transcode with the i915 igpu for plex. So far, I've tried recommendations in posts to blacklist the i915 driver (I don't know if this would disable HW transcoding in plex, but it don't work anyway) e.g., echo "blacklist i915" > /boot/config/modprobe.d/i915.conf Reboot. Same errors. I've also unplugged the kvm and replaced it with a vga dummy plug. Reboot. Same. Any other ideas? bukadoza-diagnostics-20220924-1154.zip Edited September 24, 20223 yr by brandonhowlett Added diagnostic file
September 24, 20223 yr Community Expert Yep, there is an AST GPU (for the IPMI) and it's loading the driver, instead of blacklisting the iGPU (which is not used for video out with that board) try blacklist the AST GPU: echo "blacklist ast" > /boot/config/modprobe.d/ast.conf

September 25, 20223 yr Author @JorgeB, that was the post I started with. With both the iGPU and AST GPUs blacklisted the error persists. And with the addition of a dummy vga plug, as well. bukadoza-diagnostics-20220925-0145.zip Edited September 25, 20223 yr by brandonhowlett Forgot dummy plug
September 26, 20223 yr I have a VGA monitor connected to my server. It does not stop the errors which hit the log every 2 seconds Sep 26 09:59:28 MediaNAS kernel: EDID has corrupt header Sep 26 09:59:28 MediaNAS kernel: EDID block 0 is all zeroes I have an AST (IPMI) on the server and iGPU in the E-2288G processor. I can't blacklist either as I use iGPU for transcoding and AST for KVM access to server via IPMI. Hopefully this gets fixed soon. The problem was not present in 6.10.3 which was running previously on the server. Same issue on my backup server which also has an iGPU and ASpeed chip for IPMI. No monitor is plugged into that server as it is in a closet in the basement. I guess I could try a dummy plug there but an attached monitor on main server does not prevent the errors.
September 26, 20223 yr Author I can also confirm that attaching a monitor does not fix it. Thanks anyway, @JorgeB.

Please go to Tools/System Devices and check the checkbox next to the ast device and then reboot and see if issue persists. If so, try same thing with the Intel display adapter. Checking the box for a device completely isolates it from the Linux kernel and we should be able to at least determine which is the culprit.

ASpeed bound to VFIO = EDID has corrupt header/EDID block 0 is all zeroes errors in syslog. The iGPU in the case of my servers appears to be the culprit. Edited September 27, 20223 yr by Hoopster

Yep, and probably for all having these issues, also I believe that since your board has IPMI the monitor output will use the AST GPU, so connecting a monitor won't help.
September 27, 20223 yr 2 minutes ago, JorgeB said: since your board has IPMI the monitor output will use the AST GPU, so connecting a monitor won't help. Yep, that is the case. Monitor output is via VGA connector which is controlled by the ASpeed chip.

I can confirm my results are the same as @Hoopster I also have a monitor connected via VGA controlled by the ASpeed chip. isolating the iGPU from the kernel and the error does not appear.
September 27, 20223 yr Author @limetech, I can confirm, it's the intel igpu. Same result as @Hoopster.
September 27, 20223 yr Solution We created a kernel patch in Unraid 6.11.1 to silence these messages.

December 1, 20223 yr Hello everyone, I'm facing the same issue on my Debian... after upgrading the kernel from 5.17.x to 5.19.17 I know it's not the same OS, but how did you patch the kernel to silent this log ? I only have this king of log: Dec 1 15:26:32 kernel: [21750.563946] EDID block 0 is all zeroes Dec 1 15:26:33 kernel: [21750.795510] EDID block 0 is all zeroes Dec 1 15:26:55 kernel: [21773.559925] EDID block 0 is all zeroes Dec 1 15:26:56 kernel: [21773.790095] EDID block 0 is all zeroes Dec 1 15:26:56 kernel: [21773.824563] EDID block 0 is all zeroes Thank you for any helps
