With GENERIC, I do get a different one:
Kernel page fault with the following non-sleepable locks held:
exclusive sleep mutex ATA state lock (ATA state lock) r = 0  
(0xffffff0002494988) locked _at_ /usr/src/sys/dev/ata/ata-queue.c:201
exclusive sleep mutex ATA queue lock (ATA queue lock) r = 0  
(0xffffff00024949b0) locked _at_ /usr/src/sys/dev/ata/ata-queue.c:184
