IDE drivers are in a "cold maintenance" mode, so to speak, and I don't think
this issue is going to be fixed.

Any chance to try PATA/libata instead?

Do I understand you correctly, the ide_cd_mod is legacy ide driver?

Yes, it is.  The new driver is cdrom depending on sr_mod (SCSI stack).

Can you try this one, please?  You'll need the right PATA driver for
your controller too.

With libata the bug is not reproducible, no hang processes, but
current read fails with:

[  332.456512] sr 0:0:0:0: [sr0] Media Changed
[  332.456514] sr 0:0:0:0: [sr0]  Result: hostbyte=0x00 driverbyte=0x08
[  332.456517] sr 0:0:0:0: [sr0]  Sense Key : 0x6 [current]
[  332.456521] sr 0:0:0:0: [sr0]  ASC=0x28 ASCQ=0x0
[  332.456524] sr 0:0:0:0: [sr0] CDB: cdb[0]=0x28: 28 00 00 00 51 60 00 00 40
00
[  332.456532] end_request: I/O error, dev sr0, sector 83328

This is probably expected behavior.

It could be fine with me, but AFAIR the libsata driver had pretty
fragile error handling on sense errors. When using 'safecopy' program
the kernel or device often get stuck in some weird state. Could you
take a look at it? I can try to reproduce it, but I'm not sure what
information will be useful for a bug report...

I'm not a libata developer.  Apart from this, I think it's better if you file
a separate bug under Storage IO/SATA for that issue (please put my address
into the CC list in there so that I can reassign it to the right people).

I'm closing this one as "won't fix", because I don't think anyone is going to
do anything about it at this point.

If you see problems in current kernels, please open a new bug report and
include the full dmesg log.
