This is on a simple MD RAID level 0 on two SSD drives with ext4 on top. Nothing fancy, no LVM / dmcrypt / etc. Deleting files is slow like hell, deleting big files (like 4 GB iso) hangs my system for minutes.
Where do I report it (sorry for asking, I've never reported a kernel bug before)? I'm 99% sure I should not do that on bugs.gentoo.org :)

mbar,

bugs.gentoo.org is fine. The gentoo kernel devs will pass it upsteam if its new.

Would do, but now my system is hosed by this https://bugs.gentoo.org/show_bug.cgi?id=439696 i.e. gcc-4.7.2 and some surprise buttsechs :)
Unhosing now, but I don't have 4.6.3 handy...

EDIT: reported :)
