[SOLVED] Linux kernel 3.9.2-1 bug - hp_wmi dmesg errors (hp nx9420)

bjornoslav · 2013-05-14 17:00:40

My laptop is hp nx9420, the RAM and hard drive are pretty much new and are surely fine, and I'm using 64-bit Arch. The No Execute bit has always been enabled.
Upon upgrading my system, which pulled the kernel package linux-3.9.2-1, and after a reboot, there were problems regarding the boot process and it appears it's a bug connected with hp-wmi. Also, my system can't properly unmount the root partition and reboot/shutdown.

Part of dmesg

This is the pstree upon boot and login, the tee process is suspicious:

  |-systemd-journal
  |-systemd-logind
  |-systemd-udevd
  `-tee /sys/bus/platform/devices/hp-wmi/power/control

And this is my boot parameters from Syslinux:

LABEL arch
	MENU LABEL Arch Linux
	LINUX ../vmlinuz-linux
	APPEND root=/dev/sda1 ro init=/usr/lib/systemd/systemd consoleblank=0 quiet
	INITRD ../initramfs-linux.img

I removed the powerdown package thinking it was the culprit, but it isn't.
Currently, I solved this problem by downgrading to an older kernel.

What could possibly be the cause?

Quite obviously, this is related to HP laptops. Perhaps blacklisting the hp_wmi module could solve it. However, that module might be related to the extra buttons and/or to reporting the state of the hardware rfkill switch...

Thank you very much, I shall try again with the stock kernel, since I've compiler the realtime version from AUR (3.8.11) and am using it without any problems.

Blacklisting the hp_wmi module solved the problem of the appearing error message. Thank you very much!
The extra buttons work, as far as I can see everything seems fine. Power management via powerdown works perfectly.
The WiFi/RF kill switch works properly.
