>Hi Jonathan,

content of word 62?
>If word 62 + SiI 3611 looks good, we can turn on the DMADIR
automatically. Thanks!
Per Albert's request, I've tested his patch to check the status of
word 62 with the SiI 3611 bridge chip. I used kernel version 2.6.17-
rc1, as 2.6.16 reported fuzz when I applied the patch. 2.6.17-rc1
reported an offset, but applied without any errors. I've tested with
the ATAPI_ENABLE_DMADIR workaround enabled, and disabled. Debugging
is disabled. Looks like word 62 returns 0 as its value, dmesg with
the relevant parts attached below.
If you need any more information, let me know and I'll be happy to
provide it.
