Ran into a small problem with this patch-kit on RELENG_5 ..

Jul 29 21:01:06 mail kernel: FAILURE - out of memory in ata_raid_init_request

~ .. after which the box promptly rebooted (no console, sorry).

The box is most definitely "memory constrained" (as in snippets of dmesg
below) but not so much that I would expect this. In the RELENG_5 code, memory
allocation in the driver is done slightly differently ..

#define ata_alloc_request() uma_zalloc(ata_zone, M_NOWAIT | M_ZERO)

~ .. versus ..

buf1 = malloc(sizeof(struct ar_buf), M_AR, M_NOWAIT | M_ZERO); /* XXX */

~ .. in their respective 'strategy' functions. Did the shift to 'uma_zalloc'
break my machine? ;-)
