Package: src:linux Version: 3.16.7-ckt7-1 Severity: important Tags: d-i jessie
The last line seen on the screen after installer CD boots is 'returning from prom_init'. This is a regression introduced in d-i rc2 which persist in daily builds. Connecting serial terminal and booting with 'console=ttyS0,9600' allows successful installation of jessie. (with some hiccups that warrant a separate bug report to mkvmlinuz). I'm aware that fix for bug #748398 actually introduced this regression. The radeonfb is currently compiled as module which is not included in the installer. I hope that including the radeonfb module in the installer will fix this issue. This report was generated on the same machine after successful installation. Could you please add radeonfb module to debian installer?
