Hi, We are a company which has made a small PCI card for data acquisition which we use in our radar acquisition systems. Our 'current' shipping system is 2.2.8+CAM (blerg :) and I have been attempting to validate 4.x for use, but I have found an 'interesting' interaction with a SuperMicro P6SBS motherboard.. It seems that no interrupts are being delivered, so the card transfers no data :( The same version of FreeBSD (4.1-REL) on a SuperMicro P6SBU (single channel instead of dual) and a Via Apollo MVP3 based Epox board work fine.. I have tried 2 P6SBS motherboards and they both have the same symptoms.. Everything else works (21443 network card, IDE, video etc etc), even the custom cards non interrupt related functionality is fine. This motherboard DID work with 4.0-REL, so basically I'm asking what the heck changed between 4.0 and 4.1 PCI IRQ wise :) --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
