Software Environment: Gnome/Nautilus 2.14.1 on Gentoo ~x86 (testing).
Problem Description: 2.6.17 makes file operations in Gnome very slow (something
like 10x to 20x slower than normal, I don't know exactly) and almost blocks
every other operation when doing something with files (opening xchat when
copying a file takes 20-30 seconds).
Steps to reproduce:
Upgrade to kernel 2.6.17 on a XFS partition with Gnome 2.14.1.
