The 39320A board has been tried on the Tyan 2882 and 2885 MBs with the same result: I can copy a few small files, byt when I try to copy a directory tree with a few hundred MB the system freezes without any traces in the syslog or on the screen. Two older Ultra 160 Adaptec boards work fine with the 2 Tyan MBs. The raid option has been disabled for the ASC-39320A. Tho years ago I gave up, but I have now tested the board with some newer linux distributions using the Tyan 2885 MB with the latest available BIOS (for both 2885 and 39320A): ubuntu 6.06 LTS x86_64 (2.6.15 kernel) Mandriva 2007 x86_64 (2.6.17 and 2.6.19 kernels) Fedora core 6 (2.6.18 kernel) The symptom is the same: the system freezes during the copy of files from an IDE harddisk to a SCSI disk on the 39320 controller. I am about to give up, again. Any advice is welcome. -- Bjarne
