>Description:
	On my AlphaServer 800, a freshly-compiled 3.1_STABLE kernel (checkout of June 23, 2007) kernel-panics some minutes (it varies, but it's never more than around
 fifteen) after boot with the following message:

	panic: kernel diagnostic assertion "(map->_dm_flags & (BUS_DMA_READ|BUS_DMA_WRITE)) == 0" failed: file /usr/src-3.1/sys/arch/alpha/common/bus_dma.c" line 285

	When after this, in the debugger, I type 'reboot', I get a kernel trap with
	entry 0x2 (memory management fault).

	The kernel I have been using so far, compiled on Feb 11, works perfectly.

	My kernel config:
