 I don't know if it's related to your problem, but I think the timing
 setting stuff on wdc at pci (src/sys/arch/macppc/dev/kauai.c) it's
 currently broken.

 Can you test the attached patch for kauai.c to see if your problems persist?

 It works fine for me on a Intrepid Kauai controller.
 Thanks!


 Some comments with respect to the patch:
  I think that the following lines in kauai.c (rev. 1.25):
     58 #define PIO_CONFIG_REG (0x200 >> 4)	/* PIO and DMA access timing */
     59 #define DMA_CONFIG_REG (0x210 >> 4)	/* UDMA access timing */
 should read instead:
     58 #define PIO_CONFIG_REG   0x200  /* PIO and DMA access timing */
     59 #define DMA_CONFIG_REG  0x210 /* UDMA access timing */

 Before the ppcoea-renovation branch was merged, kauai.c used
 macppc_make_bus_space_tag(regbase, 4); to map the registers so the tag
 included an automatic stride.
  After the branch was merged, it does not create a private tag anymore
 and this automatic stride is not done; so the definitions should be
 updated to reflect that (the '>> 4' shift is no longer necessary).

 Another issue is that the code in calc_timing_kauai() uses the
 DMA_CONFIG_REG register to set both DMA and UDMA access timing; but
 this register is only for UDMA; the DMA timings should go along with
 the PIO timings into the PIO_CONFIG_REG register (as the comments in
 the above lines 58-59 say).

 This can be verified by looking at Mac OS X's AppleKauaiATA.cpp
 driver, in lines 985 and 986 [1] .

 (The patch also renames the DMA_CONFIG_REG to UDMA_CONFIG_REG to avoid
 confussion.)
