In the FreeBSD newsgroup somebody mentioned the same problem, and another article mentioned as solution : upgrading of the Adaptec firmware. So I looked at my aha 1542 CF firmware (version C.0, 1993). I never (needed to) changed this configuration setting, and so had a look at them too. * I changed the settings of 'Enable Sync Negotiation' and * 'Enable FAST SCSII' of SCSI Device ID #0,#1,#2 *and* #7 from * "no" to "yes". The panics are gone. Copying from CD to sd1 is possible now..... BTW Are the firmware defaults of Adaptec changed since 1993 ? Jan van den Bosch rcjvdb@urc.tue.nl
