| phillw | Hi cjwatson is there a way to debug a perfectly working kernel that the installer states 'CD not present' which is pretty impossible as it booted off it.... The full suite is at http://phillw.net/isos/non-pae/ and the kernel runs well as it is running on that build machine... My thoughts are to a self check that defaults to that error message instead of a meaningful one that could be reported against. | 00:46 |
|---|---|---|
| cjwatson | phillw: that usually means that the driver necessary for *Linux* to access that CD drive (which is not the same stack of software required to boot from it) isn't built into the installer image | 14:46 |
| cjwatson | this is governed by build/pkg-lists/ in debian-installer plus the associated *-modules files in the kernel's build system that control udeb construction | 14:47 |
| cjwatson | in debian.master/d-i/ or some such IIRC | 14:47 |
| phillw | cjwatson: thanks, we can have a dig around. | 14:50 |
| phillw | puzzling, as I've used the .config from my existing 14.04 desktop | 14:53 |
| cjwatson | Did you rebuild d-i against your new kernel? If not, this would probably be the first place where you notice that the modules built into the installer are incompatible with your new kernel. | 14:59 |
| phillw | cjwatson: yes, I used the new kernel (It just has the pae flag turned off). | 15:22 |
| cjwatson | I'm sure that breaks module compatibility. You'll need to build udebs from the new kernel and rebuild d-i with that. Good luck. | 15:23 |
| cjwatson | http://wiki.debian.org/DebianInstaller/CustomKernel may help although I'm sure it requires some adaptation for Ubuntu. | 15:24 |
| cjwatson | https://wiki.debian.org/DebianInstaller/Modify/CustomKernel sorry | 15:24 |
