Hi, Matt, Looks like you're running out of DMA memory for some reason. On Nautilus, the DMA "zone" is configured to be 16MB (see arch/alpha/include/asm/dma.h), since there's not the usual scatter/gather support in the Irongate core logic, AFAICT. If somethings have taken a big chunk of that, say mapping regs or fbmem or some such, there may not be much left for others, even if it's only a single DMA-able page (where the "page allocation failure" message came from). I'm really unfamiliar with the code in those files (sys_nautilus.c and core_irongate.c), so I hope you can find someone more knowledgeable. Sorry. Good luck. --Jay++ Matt Turner wrote: > I'm seeing a DRM-related out of memory failure. I've filed a bug at > freedesktop.org [0], but no luck.
