Arch Linux

everytime, I try lspci, my computer(thinkpad t440p) freeze.
even boot from archlinux-2015.07.01-dual.iso usb disk

`lspci` doesn't seem to the the cause of my issue, but I am experiencing random freezes on my Thinkpad T450s quite often as well.

Agreed, lspci doesn't cause me any issues. I'm still experiencing random freezing still.

Same Problem with my Thinkpad T420.
Kernel panic after random uptime, sometimes with blinking CapsLock, but nothing in the log.

Since now, kernel panic showed to me 2 times.

I've been doing some rebasing and after reverting commit 15c1247953e8a45232ed5a5540f291d2d0a77665 I see no warning on my boot log. I'm hoping that this will also fix the freezing issue, but I'll need to work on my laptop for a while until I'm sure.

I've notified the kernel folks about this,linux-kernel@vger.kernel.org/msg949949.html"> http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg949949.html

Same problem on my Samsung np900x3c, since kernel 4.1.x, the freeze occurs only when there are bluetooth devices connected after some time (maybe when devices go in sleep mode)
Downgraded to 4.0.7 without any freeze.

-- Reboot --

The boot warning has been fixed with a patch (see above thread). However, I'm still experiencing bad crashes, I've noticed that they tend to happen after coming out of RAM suspend, but can occur at other times too. I've tried using kdump and magic sysrq to get some kind of info about why the crash occurred but the system has totally locked up. Any ideas of how to debug this, folks?

The bluetooth connection that Adriano mentions is interesting, as I have a bluetooth mouse that I use. I will try disabling the bluetooth controller and see if that prevents the crash.

It's looking like this is a duplicate of bug #45787. I've narrowed the issue down to when I disconnect my bluetooth mouse, as stated in the bug report.

same same today on two archlinux x64 installs when updated to 4.1.6-1 , downgrading to 4.1.5-1 brought both installs back up, sorry didnt read #46092

is this issue still valid?
