 I should have also repeated my "find" command test with the unpatched
 6.1.4 kernel.  I just did that and the result is consistent with my
 initial installation attempt, which is that I am unable to mount the
 CD-ROM and I get timeouts.  Here is the "dmesg" output:
 
 siside0:1:0: lost interrupt
         type: atapi tc_bcount: 32 tc_skip: 0
 siside0:1:0: bus-master DMA error: missing interrupt, status=0x61
 siside0:1:0: device timeout, c_bcount=32, c_skip=0
 cd0: transfer error, downgrading to Ultra-DMA mode 3
 cd0(siside0:1:0): using PIO mode 4, Ultra-DMA mode 3 (using DMA)
 wd2(siside0:1:1): using PIO mode 4, Ultra-DMA mode 4 (Ultra/66) (using DMA)
 cd0(siside0:1:0): generic HBA error
 siside0:1:0: lost interrupt
         type: atapi tc_bcount: 8 tc_skip: 0
