Hi,

Somehow, »atacontrol reinit« or »atacontrol detach« don't
work for me.  The processes are blocking in diskwait (ps
shows D+) and I have to reboot the machine to get rid of
them.  :-(

This is a 4.6-prerelease from 2002-05-13 (last week).

Hardware setup:
 - onboard IDE controller (intel PIIX) unused and disabled,
   thus ata0 and ata1 are not used.
 - Promise TX2 (UDMA-133) controller provides ata2 and ata3.
 - ata2 master:  Maxtor 160 Gbyte HD (ad4).
 - ata2 slave:  unused.
 - ata3 master:  24x10x40 CD-RW (acd0).
 - ata3 slave:  hot-plug IDE frame.

When I insert an ATA disk into the hot-plug frame and type
"atacontrol reinit 3", it hangs forever, and ps says:

root   62214  0.0  0.1   204   88  p0  D+    6:41PM   0:09.32 atacontrol reinit 3

Same for "atacontrol detach 3".   top says it's in state
"atalck".  It also consumes a bit of CPU time (but this is
a very slow old Pentium):

62291 root      -6   0   204K    88K atalck   0:06  3.86%  3.86% atacontrol

Is there anything I can do to get this working?
