UEFI PXE on Dell Optiplex 7010 hangs

[Sebastian Roth]

Working on this in a chat session with @BardWood it looks as if none of the current iPXE binaries work on those machines. So we will get into debugging.

Please try 01_ipxe.efi (download - compiles with DEBUG=efi_image,image_cmd,image) and post picture or video here in the forum. Best if you use the same counter which I have in the iPXE filename for the pics/vids as well so it’s easy to reference.

@sebastian-roth I just grabbed a 7010 from the build up room. Let me get setup to repeat the test here.

[george1421]

@george1421 No joy with 01_ipxe.efi or stock ipxe.efi. Stops at init devices.

Its been at this screen for 20 minutes now.

(Yes I need to clean my monitor)

Update: After about 25-30 minutes iPXE appears to abort to no bootable device (Dell firmware prompt)

[Sebastian Roth]

@george1421 Nice, thanks! So here is 02_ipxe.efi… same download link.

[george1421]

@sebastian-roth No joy at the moment. My phone hates me not sending email with picture. Last call was to 0x0xd4463b88. Posted after init devices…

Here is the pict from #2

[Sebastian Roth]

@george1421 @BardWood Next to test is 03_ipxe.efi. Please post picture of the screen when it hangs…

Could be another EFI timer issue (something we had a lot of trouble with the MS Surface devices…)

[george1421]

@sebastian-roth I’m home right now, but I did update the picture. I’ll hit 03 in my AM tomorrow.

[BardWood]

@sebastian-roth
Here is from 03_ipxe.efi (after chmod 655)

Sits there for 15 mins or so and reboots

[Sebastian Roth]

@BardWood Ok, thanks! Sure I was wrong about the EFI timer, thank god.

@george1421 HAHAHAHA… I’ve been there… years ago. But couldn’t remember. LOL See here: http://forum.ipxe.org/showthread.php?tid=7877

[Sebastian Roth]

@BardWood Here is 04_ipxe.efi (compiled with DEBUG=init,runtime,efi_timer,device,pci option). Please try again and post a picture.

[BardWood]

@sebastian-roth 04_ipxe.efi:

[Sebastian Roth]

@BardWood Ok, here is ready to go 05_ipxe.efi (DEBUG=init,efi_utils,efi_driver,efi_pci). This time I guess you need to take a video of the messages passing by on screen. Make sure to rest the camera/smartphone e.g. on a pile of books so we get a decent steady picture. Would be great if you could even take a video with 60 fps which most smartphones are capable of these days!

But if there’s too much output on screen and you can’t take a proper video you might test 06_ipxe.efi (DEBUG=init,efi_utils,efi_pci)…

@george1421 Re-reading all the stuff we tried back in 2015 I get the impression that the issue with those 7010s is that for some reason the native Intel driver is not being used. Then it tries SNP and for some reason that fails. More or less a guess though.

@sebastian-roth

RE: 05 = Wowsa! Yea, much output. My phone won’t let me video yet because the battery is too low (???). I’ll capture a video later but I cant even read it in person it scrolls by really fast. I’ll do what I can.

RE: 06 =

[Sebastian Roth]

@BardWood Ok, seems like it actually does see it as being a proper Intel NIC. I think we are on the right track. Though it definitely needs more work than I had expected. Keep it up and hopefully you can get a good video (60 fps!!) of it. This is where digital devices have a great advantage over our eyes.

[george1421]

@sebastian-roth Well let me say I’ve very disappointed in this latest iphone upgrade. Its really driving me crazy at the moment.

I finally have the download figured out. I’ll get you the link to the 05 = Wowsa! video in a moment, or when ever my iphone decides to email me the video

@sebastian-roth Unfortunately I can’t capture 60 FPS video on a Motorola Droid Turbo. I thought it was an artificial limitation since the camera is capable of it spec-wise but when I tried in Open Camera, I got the same message. I’ll see if I can get our photographer buf to do it on her iPhone 6.

[BardWood]

@sebastian-roth OK have a ~1Gb video file I’m trying to upload to flickr of 05 but a quick glance tells me it’s scrolling the same info in a loop. Here is a screenshot:

[BardWood]

@sebastian-roth here is the video of 05 on flickr https://www.flickr.com/gp/138098812@N03/D0569a

[george1421]

@bardwood FWIW: Your video is repeating in the same spot as mine.

It would be interesting to know what is causing the “Disconnecting existing drivers” line to post. I think that may be the root of the issue.

[Sebastian Roth]

@BardWood Wow! You’ve done an amazing job getting a stable picture with the camera and I am sure we got all the information from that debug build in the picture you posted! I am still watching the video just to make absolutely sure we don’t miss anything else. Thanks heaps for that.

I will dig through the code and hopefully will find what’s up here. Though we might need to do more of these rounds I’m afraid.
