Used all but 70MB of memory. No hangs. The weird thing is that crashme was supposed to run for 8 hours but it's been running for over 14 hours now. Any ideas? Also, I don't think this was a particularly good test of highmem since I don't think many bounce buffers were used, or that the kernel had much reason to map/unmap many highmem pages. Unfortunately, my SCSI controller isn't working quite right and I can't test with a hard disk as a result. Any ideas for stressing the system harder? -VAL ** Sent via the linuxppc-dev mail list.
