Problem Report:

Kernel fails and generates a error message when trying
to enable UDMA in ATA hard Disk.

Confidential:
No

Priority:
High


Originator:
Abbas Karbassian <abbas_karbassian@yahoo.com>


Release:

FreeBDS4.7-RELEASE i386


Environment:
FreeBSD  4.7-RELEASE FreeBSD 4.7-RELEASE #0: Wed Nov
27 17:23:59 GMT 2002  
root@:/usr/src/sys/compile/KERNEL47  i386



Description:


I have recently installed FreeBsd4.7 from DVD.
I have added the following line  in /etc/rc.local file
to enable the highpoint366 UDMA.


"sysctl -w hw.atamodes=dma,dma,dma,dma"

during boot up time the following message displayed on
the screen:

"Starting local daemons : sysctl :unknown oid
'hw.atamodes' "

This feature was working correctly in FreeBsd4.5, and
It has been broken in FreeBsd4.6 and FreeBsd4.7.



How-To-Repeat:

1-) Create rc.local file in /etc directory.
2-) Add the following line in to rc.local file.

sysctl -w hw.atamodes=dma,dma,dma,dma


Reboot the P.C, and monitor the error message during
the boot time.


Fix:

I do not know, since all the files since FreeBsd4.5 is
changed so much, and It is very difficult to see what
is going on.
