Most if not all modern aosp Roms like aokp, pacman, and others use the same kernel source. I am using a cm10.2 based rom on my tablet but, a kernel should not effect superuser. What errors are you getting? Have you tried updating Superuser or supersu which ever one is installed?

When I tried to run Titanium Backup, but it kept telling me that it did not have root.
I tried installing and updating each of the Superuser and SuperSU separately without success. When I re-flashed the PAC 4.3 rom, things went back to normal.

i installed this kernal and can no longer get root. Are you having this problem. I am on kaspers Omni rom as well.

I had the same issue and had to re-flash the rom. Looking at the file, it looks to be for CM based rome only.

Nope, i have no issues at all, flashed it and works perfect since day one, still using same ROM and this kernel, it's just perfect for me like it is now :)

    I'm flashing it too... In a few days I'll let you know how it works with a P4 running kasper_h Infamous PAC ROM.
    Thank you in advance for your work!
    Any worries if I use kasper_h TWRP recovery?

    Nope.

    Found a problem. Reboot doesn't work. I'm guessing its because of the linaro toolchain since kasper's infamous kernel had this issue too when he compiled it with linaro toolchain.

    I could make one. Just will need a willing tester.

    I can test it. :)
