No mouse and keyboard in stretch amd64 installer

#1 Post by herostratus »

Hi,

I have Asus Z87-PRO motherboard with i5-4670k and I'm trying to install Debian Testing with 64-bit architecture. My problem is mouse and keyboard (I guess USB in general) stop working after installer get loaded (the last thing I do is choose between text and graphical install). I found a few topics on different forums indicating that I should enable IOMMU (Intel VT-d) option in my bios. The problem is that Intel k-series processors didn't use to have IOMMU support, so there's nothing I can do about it. I tried changing different bios options like disabling UEFI, enabling xHCI and EHCI with no luck. Passing "iommu=off" or "iommu=soft" to the boot command also doesn't help. However, I have LMDE 2 64-bit live cd (based on Debian Jessie) and it works fine, so I guess my problem may be related to some changes in 4.2 kernel.

Any help?

It's a known bug: https://bugs.debian.org/cgi-bin/bugrepo ... bug=802618

This is the kind of thing that has to be expected in both Testing and Unstable. If you had installed "apt-listbugs" first, you would have been notified about this bug, and could have aborted the upgrade before you got yourself into trouble.

Now I will lay one ground rule for anyone who ever thinks about doing a upgrade to Testing/Unstable. INSTALL apt-listbugs before you even think about upgrading. Because apt-listbugs isn't only recommended, it is a 100% must, and it's also a must to check every single grave and serious bug reported, before deciding whether to upgrade or not.

Here is one thing you can try: (in terminal, copy the whole line and paste it into the terminal, and hit enter)

Code: Select all

sudo apt-get update && sudo apt-get install -- reinstall libpam-systemd
Then reboot...

Thanks for the link.
I'm Debian user for over 10 years, so I'm fully aware of risks when using testing/sid. I ran into this problem not after upgrade but during clean install. If there is a missing dependency and xorg-server-core was upgraded in testing on Monday, so probably the previous weekly build iso will work fine. I will check that later.

Okay, I checked other installers with no luck. Jessie and Stretch alpha 3 don't even boot on my hardware. Stretch alpha 4 (released today) boots properly, but after loading the installer there's still no input. Text install doesn't work neither, so I don't think it could be X server related bug.
I suppose the culprit is my CPU which is the only Haswell i5 with no IOMMU support.
Any other ideas or should I go with bug report?
