How so if they are mentioned in the oops in comment 0?

blk and net is loaded, but fb and kbd is missing in initrd.

The only modules in the initrd are loop and squashfs. Are the rest built into the kernel itself? As I mentioned in comment #2, hacking more modules into the initrd does not seem to help.

The initrd contains a compressed image which contains additional drivers. Guess I need to fork the pkg and do a pull rq.... -- You are receiving this mail because: You are on the CC list for the bug.

Thanks, but I don't think that's enough... I manually tested this change, and the installation gets slightly further, but then encounters the following errors:

I manually changed the module.config file (in the squashfs 00_lib, in the initrd) to specify the dependencies on the fbfront driver as follows: xen-fbfront,,,sysimgblt sysfillrect syscopyarea fb_sys_fops However, I still see the same "Unknown symbol" errors. (All required modules are in the lib/modules/4.4.0-3-default/initrd directory, within the 00_lib fs.)

Also, module.config is only used in case linuxrc itself needs to load modules (which it normally does not do). Otherwise module loading is purely an udevd/modprobe business. If a module is missing, do you have an idea which one? -- You are receiving this mail because: You are on the CC list for the bug.
