trouble with adaptec 2904 + CD-W Taiyo Juden

[matteo]

My SCSI chain is composed by: adaptec 2904 + plextor CD reader ( SCSI ID
3)+ Taiyo Juden BW-50 CD recorder(2x write 4x read) (SCSI ID 1). I run
RH linux 7.0 with kernel provided by installation + win NT 4 Workstation
(dual Boot)
When I boot the system, the SCSI adapter is properly recognised, but
when begins the devices identification, the aic7xxx drivers logs:

(scsi0:0:1:0) Syncronous at 4,4 Mbytes/sec, offset 15
SCSI: aborting command due to timeout: pid 1,scsi 0,channel 0id 1, lun 0

        Test Unit Ready 00 00 00 00 00
SCSI host 0 abort (pid1) timed out - resetting
SCSI bus is being reset for host 0 channel 0

These lines goes on till i reset the system.
When I disconnect the CD writer ( so only Plextor is connected)
everithing works ok under linux, while when i boot win NT with CD reader
+ CD
writer everithing works ok.
I also used this configuration ( CD reader + CD writer ) under RH linux
7.0 but with an adaptec 1520 (ISA) and I've never had any trouble.
Can anybody tell me what to do?
Thanks

P.S. the default host adapter settings are:
SCSI ID : 7
parity checking : enabled
transfer rate:  10 Mb/sec
Sync negotiation : enabled
Fast SCSI: enabled
Disconnection: enabled

they are fixed and they can not be changed
