IDE Hardisk Problem when setting drive to standby mode with hdparm

Hi there,
I have two disks on my primary IDE-controller. The first one (hda) is the one where grub is installed. On the second one (hdb) is Linux installed. Because hda is the older (slower and much more noisy) drive, I use it as a backup device. But of course it does not have to be on all the time. So I set it to standby mode with `hdparm -y /dev/hda`. But after 30 minutes it wakes up. Even if it's unmounted. Since it is a very noisy drive, this is very ugly for me. When I set the drive to sleep mode with `hdparm -Y /dev/hda`the it does no more wake up (only with the appropriate commands). But the bad thing is, that again after 30 minutes the system freezes for about three seconds. And the message
Jul  4 06:25:37 shiva kernel: hda: lost interrupt
is printed to the syslog.

This is an ASUS TUSL2 Motherboard BIOS Rev. 1006 with all power management futures disabled.
The Disks: hda: IC35L040AVER07-0, ATA DISK drive
hdb: ST3120026A, ATA DISK drive
Both are set to DMA-Mode and 32-Bit access mode (with hdparm -c and hdparm -d).

Distribution: Fedora Core 2 Kernel 2.6.6-1.435. The ACPI and APM futures are turned off via the boot-cmd-line in grub (acpi=off apm=off). The apm daemon (apmd) is of course also turned off.

This problem is new since I reinstalled to Computer with Fedora Core 2. Before I had RedHat 9.

Any hint for this problem?
