Now this may or may not be specific to openSUSE, but here it is anyway:
I suffered from desktop lockups when copying large files, for instance from the wireless network to usb. THis was especially noticable in dolphin.
Even though I suspected it at first, now it appears that it is not dolphin that is acting up, it is the 'hugepage' option in the kernel.
So, how do we tweak it? Simpel. The following lines will do the trick as root:
echo never >/sys/kernel/mm/transparent_hugepage/defrag echo 0 > /sys/kernel/mm/transparent_hugepage/khugepaged/defrag
-edit-
echo never > /sys/kernel/mm/transparent_hugepage/enabled echo madvise > /sys/kernel/mm/transparent_hugepage/enabled
