It may only occur on the 7880 based controllers. Do you have any older 2940Ws around? >Should I be able to duplicate this in -stable, or does this problem >only seem to be occuring with -current? I only enabled parity checking for the aic78X0 family recently in -current. I didn't even think much about it since it was an oversight that it wasn't enabled before and it has been enabled for some time on the aic7770 chips. The setting tracks what is set in SCSI-Select so its easy to change. I should have the -current driver pulled back into -stable soon (minus the parity stuff). I'll send you a private patch to enable the parity once I do this. >-- >Rod Grimes rgrimes@gndrsh.aac.dev.com >Accurate Automation Company Reliable computers for FreeBSD -- Justin T.
