HP Stream 11 x360 (HP 11-ab00x) Hangs after init.xz

[Sebastian Roth]

@JJ-Fullmer Thanks for the pictures! I am fairly sure I know what is causing the hang on this device. Is this a HP x2 210 tablet??

I’ll compile a special kernel image for you that skips some PCI initialization code that is causing big troubles on some devices (namely that HP x2 210)!

So no it’s not an HP x2 210 tablet, but I wouldn’t doubt it’s got enough similarity to have the same problem being an HP x tablet.

@Sebastian-Roth I also tried various old kernels from the fog kernel update (giving them different names of bzImage of course) non of which worked but had either similar errors or just hung.
So a special kernel is greatly appreciated.

[Sebastian Roth]

@JJ-Fullmer Ok, here we go, try this kernel: https://fogproject.org/kernels/Kernel.SR.SKIP_PCI.4.8.11.64

[JJ Fullmer]

@Sebastian-Roth Sadly it just hung as well. Thanks for giving it a try though, I know compiling a kernel isn’t a 2 second process.

@JJ-Fullmer As the kernel code is changing and I never saved that dirty hack as a proper patch I need to make this up again from memory all the time. So possible my hack was just wrong the first time. I now added some debug output to see if I am doing things at the right place. Please download from the same URL again, I just updated the binary a minute ago: https://fogproject.org/kernels/Kernel.SR.SKIP_PCI.4.8.11.64

@Sebastian-Roth Gotta love how reflective this computer’s screen is…Took a picture of the debug output

@JJ-Fullmer Ohhhh my …, must have lost track of this in the middle of a hectic months. Sorry! Do you still have those devices at hand to test?

[JJ Fullmer]

@Sebastian-Roth I do still have it on hand if you have any new ideas. I just ended up going through my image prep process with a fresh install of windows as if I was making the image on this computer. It was much much slower of course, but it worked. This one in particular has been deployed now, but if we have something promising I could probably pull it back from production and give the user something else in the interim.

[Sebastian Roth]

@JJ-Fullmer I’ll look through the code again in the next days and post new kernels to test if you are available and have a device to test.

[Sebastian Roth]

@JJ-Fullmer Sorry for the long delay again. I am back on track now to tackle this. Do you think you can get it back for some testing in the next couple of days? I am preparing debug kernels already. So I’ll be ready to go when you are.

[Sebastian Roth]

@JJ-Fullmer Ok, I just prepared a first one to test for you - download 1_bzImage and put in /var/www/html/fog/service/ipxe. Then edit this host’s settings and set this kernel as Host Kernel and see what you get.

I used a fairly recent kernel version 4.19.13 and so we might even see different behaviour than when we tested some months ago.
