Hi, I use FC5 on an MSI KT4A-V [1] and an AMD Athlon 2800+ CPU. Kernel is kernel-2.6.18-1.2239. When booting, I got a "soft lockup detected on CPU#0". 2.6.15 kernel (the one instaled at install time) works fine. Would you know an existing bug I could confirm or should I open one? I already searched, and there are many similar problems. What to do then?
