According to Julian Elischer: > the intel PLATO is OK but there are problems... > > The problem is not "completely" solved. What I did try at the end is to use all the "new" aic7* files that drive the Adaptec 2940 with the "old" 950412-SNAP kernel. Now the things work, but I discovered, what, probabilly, is the problem with the Intel Plato Board. The new version of the aic7* files in -current showed me that the Intel Plato is using "edge-triggered" interrupts by default on PCI, instead of "level-sensitive". The Plato's BIOS initialize the card that way. I recently posted to freebsd.msc and linux.hardaware about that, but withous any new answer. There was also some post in the freebsd hackers mailing list about that. Furthermore this doesn't explain why the old 1542CF ISA controller seems to have a related problem (I cannot test it anymore, I haven't it on my hand now). Just to finish -current aic7xxx.c show me that the card 2940 is using edge-triggered IRQ. Should I set the PCI_EDGE_INT pci option to compile my kernel for this MB? What would be the performance penalization in this case? Does you would suggest to buy the Plato? Or would be better an ASUS or the new Intel Zappa? Does any way to set the IRQ to level-sensitive exist around? Thanks, Peppe. -- Giuseppe Vitillaro
