[Pkg-sysvinit-devel] Bug#426224: The fix for SATA disk shutdown introduced a new bug for some IDE hard disks

[Hubert Verstraete]

Hi debian bug 426224 and Werner Fink.

Werner, I'm CCing you because, this bug comes from the patch you've done 
for sysvinit, which has been used to fix the debian bug 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426224

First I confirm that sysvinit/2.86.ds1-40 fixes the shutdown issue of my 
SATA hard disks.

Nevertheless since sysvinit/2.86.ds1-40, I have some error messages on 
the IDE hard disk hda when the computer is shut down.
The error messages are:
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }
failed opcode was 0xe7

The line in the source code which triggers this error is this one:
ioctl(fd, HDIO_DRIVE_CMD, &flush2);

When I remove it to have a behavior closer with the one in 
sysvinit/2.86.ds1-38, the error does not occur any more.
This is probably because this Flush Cache command is not supported by my 
hard disk model; another IDE hard disk I tried did not have this issue.

Here is the information from one of my hda hard disks having this error:

# hdparm -I /dev/hda
