PROBLEM: buggy ide-scsi

    ide-scsi not working on kernel 2.5.8

I try to burn cds on a 2.5.8 kernel (debian distrib) using kreatcd (and 
gtoaster) on a Ricoh Ide Cd Writer using the ide-scsi and a unexpected 
error occurs. Using the same config, when I boot on a 2.4.17 kernel, 
there ain't no problem.
Did you change anything ? The ide-scsi module hasn't been maintained 
since Jul 4, 1999 (kinds of 2.2.x period, no ?).
Did configuration change (i tried to turn over, no way...).
In fact, something worrying me. I use the ide-scsi as a module, and 
while no cd burner is launched, lsmod tells me it's used (only in 2.5.8 
kerns, in 2.4.17 it's unused). I wonder if it's not the [scsi_eh_0] 
kernel thread which tries to use it (what for ?). Maybe this is what 
blocks the use of ide-scsi...
I'll try to debug it my way, but it will take ages....

If you have any clues, tell me.

Thanx

F.-E.

As a matter of fact there where significant changes to
the way block IO requests get handled in the IDE driver.
(TCQ stuff).
Due to this several (all?) of the drivers different from ide-disk
are now nonfunctional until they get adapted to those
changes. Please be patient, since this is certainly going to take
some time.
