As mentioned in my first comment, this bug also affects the netboot installer at e.g. http://gb.archive.ubuntu.com/ubuntu/dists/bionic/main/installer-i386/current/images/ so it is still not possible to boot the installer in 32-bit under Xen. The main OS kernel has been fixed but not the installer

Hi Joseph, As this problem only affects 32-bit, there would need to be an i686 kernel there. As far as I can see there are only amd64 packages. I have already tested this patch on the linux source package from 18.04 (comment #9), but I don't have the binary packages around any more. If you want

I built a test kernel with the patch posted in comment #12. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1789118 Can you test this kernel and see if it resolves this bug? If it does, I'll submit it as an SRU, so we don't have to wait for the patch to come down

Alternatively as the bug is in the EISA code, if the kernel was built without CONFIG_EISA=y then I think that would avoid it. I haven't hit this problem on Debian stable or testing where CONFIG_EISA is not set. -- You received this bug notification because you are a member of Kernel Packages,

Okay, I went back through the kernel PPAs and in fact the most recent one that I can get to boot under 32-bit PV mode Xen is 4.13.16. 4.14-rc1 does not boot. I realised then that it was possible that I had never tested any version of 32-bit Ubuntu 18.04 under Xen. It is possible that I only ever

Sorry, I requested testing of the 4.15.0-33 kernel, but should have requested 4.15.0-32. Yes, it would be great if you could identify the last 4.15 kernel that booted and the first that did not. Once we know this, we can perform a bisect to identify the commit that introduced the regression.
