Hi

This is an OLD problem of NetBSD with the LiteON CDRW drives , I've 
reported this yet on the "port-i386" mailing list sometime ago , and 
with me some other people have replied to that accusing this very very 
very annoing problem .

I hoped that this would be fixed in the meantime (from 1.6 or 1.6.1 , I 
don't remember , but some months ago , anyway) , but this hasn't been 
fixed .

The problem is this :
My model  is LiteON LTR-52246S , I use the lastest FirmWare

The drive seems to be recognized correctly , and I can put a CD inside 
it and use it for while the CD is still running in the device , but if 
the CD stops running in the device , because the CDRW drive has not been 
accessed by a few time when I try to access to it again I get this error :

pciide0:1:0: lost interrupt
             type: atapi tc_bcount: 0 tc_skip: 0
pciide0:1:0: lost interrupt
             type: atapi tc_bcount: 0 tc_skip: 0
 pciide0:1:0: dmamode timed out


These messages continue to appear on the screen , until I reload the 
device .

I don't know why NetBSD has this LOST INTERRUPT on this device , Linux 
and FreeBSD stable have ever worked well .

Please , solve this , because I'd like to give a try to NetBSD,  but 
this stops me :-(
