Bug#792540: Wifi netinstall fails with flashing screen on Lenovo X220
Package: debian-installer
Version: debian-8.1.0-amd64-netinst.iso
Severity: important
Tags: d-i
I tried to install Jessie on a Lenovo X220 using netinst on USB
flash drive, without Ethernet connection, but with the non-free
iwlwifi drivers .deb on an SD card (either internal slot or USB
adaptor).
After the very early step of selecting the keyboard layout, the
installer seems to try to start X or something, but seems to fail.
The screen flashes "for ever" and installation cannot be
continued.
Workaround:
If I use Ethernet instead of Wifi and do not use the SD card,
the installation continues.
Btw, debian-7.8.0-amd64-netinst.iso shows the same behaviour.
