Comment 5 for bug 1789118

32-bit kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.18/linux-image-4.15.18-041518-generic_4.15.18-041518.201804190330_i386.deb does not boot, in fact it crashes immediately without producing any console output at all (so doesn't get as far as the currently-packaged linux-image-generic).

The 64-bit package http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.18/linux-image-4.15.18-041518-generic_4.15.18-041518.201804190330_amd64.deb boots and seems to behave as expected.

Would it help if I went back through package versions of linux-image-generic until I find one that does boot? I know for certain that one of them does because this was encountered only after an update.
