Have you tried the driver in -current and/or 6.1-R? Specificly v1.14 and v1.13.2.1 of iir.c that limits the simq to 32 commands? We are running w/ this modifications w/o issues on 6.0-R w/ SRCU31A and SRCU42L cards... We have a few GDT cards also that I don't believe we are having any issues with... Infact, scottl tracked down that change after a bit of proding from me on behalf of my employer nCircle... (Though it helped that he was able to reproduce it in his lab.)... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
