Hi, I have a kernel 4.2.5-1-ARCH and I have the problem...In dmesg:

I have the module i915.
I probed this in the grub /etc/default/grub
GRUB_CMDLINE_LINUX="i915.powersave=0" And:
grub-mkconfig -o /boot/EFI/grub/grub.cfg
But the kernel panic persist... Can I help me please?
Kernel 4.2.5-1-ARCH. I think solved in the kernel 4.3-rc ...
Could try install linux-git?
I have resolved it with this: http://ubuntuforums.org/showthread.php?t=2284315&page=2 ------------------ I have posted the complete process that I followed to get it set up earlier on in this thread but I will post it again here for convenience. Here it is: 1. You HAVE to install ubuntu 15.04 64bit. Any other version simply does not work. 2. In the BIOS you have to disable the following: FastBoot, Intel Speedstep, SecureBoot 3. In the BIOS make sure that UEFI is enabled with CSM 4. When starting the Ubuntu installation you have to add the kernel option "libata.force=noncq". This is a MUST! 5. After the installation do a full update on Ubuntu. Then you can remove the kernel option "libata.force=noncq". Your SSD should perform faster now. But SpeedStep is still a problem. I have to keep it off. 6. I even re-enabled Fastboot and Secure in the BIOS and it still runs fine. --------------------- It works!!!
