Subject[IDE]2.4.0test9-pre1, CD drive on hpt366 not detected correctly and locking up when activated
The subject says everything, while detecting the drive

i got the following strange thing:

[from dmesg]

>PIIX4: chipset revision 1
>PIIX4: not 100% native mode: will probe irqs later
> ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio

^^^^^ suddenly got one

I've done some inquiries with hdparm:

[root@Djinn dea]# hdparm -i /dev/hde

/dev/hde:

Model=, FwRev=, SerialNo=
Config={ SpinMotCtl Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=8224
BuffType=8224(?), BuffSize=4112kB, MaxMultSect=32, MultSect=off
DblWordIO=no, maxPIO=32(?), DMA=no
(maybe):

[root@Djinn dea]# hdparm -I /dev/hde

/dev/hde:

Model=RC2-08T1 E , FwRev=.101 , SerialNo=
Config={ SpinMotCtl Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=2(DualPort), BuffSize=0kB, MaxMultSect=0
DblWordIO=no, maxPIO=3(eide), DMA=yes, maxDMA=1(medium)
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
tDMA={min:150,rec:230}, DMA modes: ***sword2 **mword1
IORDY=on/off, tPIO={min:180,w/IORDY:180}, PIO modes: mode3

When these were performed i got this in logs:

VFS: Disk change detected on device ide2(33,0)
ATAPI device hde:
Error: Not ready -- (Sense key=0x02)
(reserved error code) -- (asc=0x3a, ascq=0x01)
The failed "Read Table of Contents" packet command was:
"43 02 00 00 00 00 00 00 04 00 00 00 "
VFS: Disk change detected on device ide2(33,0)
ATAPI device hde:
Error: Not ready -- (Sense key=0x02)
(reserved error code) -- (asc=0x3a, ascq=0x01)
The failed "Read Table of Contents" packet command was:
"43 02 00 00 00 00 00 00 04 00 00 00 "

Please note the "Disk change detected": i haven't touch the drive between

the two hdparm.

When i attempt to mount the drive, the whole system got stuck with nothing

in logs(even on serial console).

I've tried different configurations(multimode on/off, reset ide2 on start, etc..)

the result is always the same: lockup when mounting and garbage in logs

when hdparm.

Feel free to ask for more tests or for my whole .config.
