FreeBSD's strategy for doing page coloring makes contiguous memory allocation much past boot quite difficult. This will change when generalized superpage support is brought in (I hope in the near future).

Hi, I sometimes see that the USB driver is unable to allocate contiguous memory for itself. For example I noticed that FreeBSD was unable to allocate 350kbytes of contiguous memory after that I had run "konqueror", the KDE web browser and various other memory consuming applications for a while. I am thinking about pre-allocating some memory for USB, but isn't that the job of bus-dma, which the USB system uses for memory allocation? The machine in question is running FreeBSD 7-current from April. Any comments?
