Re: After kenrel upgrade HTB is not accurate 3.11.6.x

["Hoggins!" <fuckspam@wheres5.com>]

Hello,

Seeing that I'm not alone having issues with HTB on newer kernels is
quite relieving. I discovered my problem yesterday, and my only solution
so far was to downgrade the kernel to an acceptable version floor.
Working with kernel 3.10.25 did the trick. I'm sorry, as I cannot help
any further, and my knowledge is really limited on this.

Good luck !

    Hoggins!
