Thinkpad R40e can't boot Debian 9.0.0 netinst image without acpi=off
Hi,
I wanted to file a bug report, but I don't know which package the issue
belongs to.
The computer is a IBM Thinkpad R40e.
Currently Debian 8 is installed. Ever since Debian 8 was installed on
the harddrive I had to add acpi=off to the kernel options, otherwise the
computer does not boot. No other acpi/clock/irq option mentioned on
Internet works. Blacklisting the acpi_cpufreq or any other acpi* module
does not fix the issue.
The Debian 8 live CD image used to install the system does not have the
issue. The previous OS was Debian 7 Wheezy and it did not have the
issue.
Now I'm trying to upgrade to Debian 9 by reinstalling the system from
scratch. I've downloaded the debian 9.0.0 netinst install.
The netinst image is copied with command dd to an USB key.
The computer boots on the key and the first menu appears.
I select "Graphical Install".
The light on the USB key blinks a few minutes.
After a while, the screen goes black with a static(=not blinking) text
cursor in the corner. No disk, USB or other activity visible. No
reaction to Ctrl+Alt+DEL or any keypress. The computer is stuck in that
state and only a poweroff (hold powerbutton 4 sec) does work.
Pressing TAB in the menu when "Graphical Install" is highlighted and
adding acpi=off to the kernel options does prevent the lock and allows
the graphical installer to start.
I repeated the same steps with the Debian 8.6.0 netinst image and the
issue is not present (at least not until Debian is installed on the hard
drive).
I guess there was some change in kernel config after the Debian 8 live
cd/netinst images were built. This change prevents the default kernel
from booting on the Thinkpad R40e. This change is now part of the Debian
9.0.0 netinst image.
