I have now tried Rawhide 3.15 on three machines. A Core Duo E8500 (which only reports one core) runs fine. An I5-3550 is somewhat unstable. Interestingly, it fails Test 7 on Memtest86+ 5.01 in SMP mode. Others have reported the same problem with various machines. The memory test passes without SMP mode. An I7-3770K runs in 3.15 text mode but immediately freezes when X is started. Anaconda 21.31-1 works but in rather low resolution. I tried it without the Nvidia card, using the on chip Intel gaphics and got the same freeze. This machine runs Win7 and Heisenbug without crashing. This machine ran Memtest86+ 5.01 in SMP mode without issues. I will leave Memtest running for a while to make sure it is stable. -- Chuck Forsberg WA7KGX caf@xxxxxxxx www.omen.com Developer of Industrial ZMODEM(Tm) for Embedded Applications Omen Technology Inc "The High Reliability Software" 10255 NW Old Cornelius Pass Portland OR 97231 503-614-0430 -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
