Many of above are still seen on the latest current.
malloc() of "16" with the following non-sleepable locks held:
exclusive sleep mutex g_xdown r = 0 (0xe044eca8) locked _at_ /usr/src/sys/geom/geom_io.c:355
malloc() of "16" with the following non-sleepable locks held:
exclusive sleep mutex g_xdown r = 0 (0xe044eca8) locked _at_ /usr/src/sys/geom/geom_io.c:355

Perhaps it's a ServeRAID specific glitch?

ips0: <IBM ServeRAID Adapter> mem 0xf0000000-0xf3ffffff irq 16 at device 1.0 on pci4
ips0: logical drives: 1
