I am running latest Gentoo on my AMD 64 machine, in 64 bit mode. My primary disk is on a SIL fakeraid on 2 mirrored sata disks. I am running device mapper, udev, and dmraid. have my root partition using reiserfs (version 3). When I do large cp operations (like copying a 2GB file), my system locks - slowly. Like over several minutes the system becomes less and less responsive, as if the load or memory use is rising until it finally locks up completely. This problem is reproduceble. A hardware reboot is needed every time. There is no messages in the kernel log that indicate the problem. Has anyone seen this? How do I investigate it? 2.6.11-gentoo-r6 x86_64 AMD Athlon(tm) 64 Processor 3200+ AuthenticAMD
