Miquel,
Could you please update your sym53c8xx driver version and let me know if
it makes differences.
If you read the linux-scsi list, you probably didn't miss my recent
posting that explained how old the [ncr/sym]53c8xx drivers are in
linux-2.2.X compared to latest drivers. If you missed my posting, let me
know and I will forward you it.
Regards,
G�rard.
