I tested the patch. - 3 x "make -j8 buildworld" : no machine check exception - mount nfs filesystem on the server an copied 10G of small files to local zfs: no machine check exception > Most likely this will fix the buildworld scenario. > But I am not sure if it will fix ZFS scenario. > If it does - then great, if not, please apply the following patch in > addition to the previous one and test again: If related zfs issues come up in the next weeks, I'll contact you. Server now runs stable with superpages set active. Nice! --Kai.
