Architecture: m68k
Machine: mac68k
>Description:
IDE disks attached on wdc0 at obio0 (at least) my LC630 doesn't
respond (looks no interrupt) on NetBSD/mac68k 9.3 INSTALL, GENERIC,
and WSFB kernels.

Note wd(4) works without problem on NetBSD/mac68k 8.2 INSTALL kernel.

>How-To-Repeat:
Just boot NetBSD/mac68k 9.3 kernels (INSTALL, GENERIC, or WSFB) on LC630.

>Fix:
Unknown.

There are major attachment changes for NCQ support between
netbsd-8 and netbsd-9, but changes in mac68k/obio/wdc_obio.c looks okay
for me.

 Hi,

 This should be due to regression for driver with ATAC_CAP_NOIRQ.

 This has already been fixed for -current:

 http://www.nerv.org/netbsd/?q=id:20211005T080105Z.58ea48edc6512b481d4fa1baba2562a3bb604d51
 http://gnats.netbsd.org/56403

 I should have pulled this fix up to netbsd-9, but I couldn't test
 netbsd-9 branch at that time.

 The above-mentioned commit can be almost mechanically applied to
 netbsd-9. Can you please test this patch? (only compile-tested)

 https://gist.github.com/rokuyama/5570ca0866b3b4d44330cc4d417a9148

 Thanks,
 rin
