I have an Athlon64 box running Fedora 2 x86_64 (whose default kernel is 2.6.5). The 2.6.5 version works perfectly... The problems start when running a kernel later than 2.6.5 (I have tried with 2.6.6, 2.6.8 and 2.6.9). If I select any of those kernels to boot, I get an error message "BIOS Error: No PSB" during kernel initialization, but the start-up goes on... When trying to start X, the system freezes (after a malformed image is drawn on the screen)... While running Fedora 2, I am actually able to get the system up @ runlevel 3, and, depending on the Cool and Quiet setting on the bios, I get two different error messages: SNIP: --- - With Cool & Quiet DISABLED in bios: powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) powernow-k8: BIOS error - no PSB This is obvious, as Cool and Quiet is disabled, powernowk8 would not work... - With Cool & Quiet ENABLED in bios: powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: invalid freq entries 3300000 kHz vs. 2147483048 kHz powernow-k8: 0 : fid 0xe (2200 MHz), vid 0x2 (1500 mV) powernow-k8: 1 : fid 0xc (2000 MHz), vid 0x6 (1400 mV) powernow-k8: 2 : fid 0xa (1800 MHz), vid 0xa (1300 mV) powernow-k8: 3 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV) powernow-k8: cpu_init done, current fid 0xe, vid 0x0 powernow-k8: ph2 null fid transition 0xe Any clues in here? --- Well, those results are with the 2.6.9 kernel from Fedora 2, @ runlevel 3. When I tried to update to Fedora 3 (which uses the 2.6.9 kernel as default), I was not able to boot @ runlevel 5 (with the same strange image drawn on the screen), but neither @ runlevel 3 (i got a kernel panic error, which I didn't give it enough time to analyse, as I needed the machine working; I just ended up reinstalling fedora 2). The thing is: on the same machine, if I boot with kernel 2.6.5, the system works fine, but with 2.6.9, X won't start (the machine freezes). Dave pointed out that this probably got fixed on 2.6.10rc1. Can anyone confirm that? Will I be able to boot with kernel 2.6.10 (once it is released) ? BTW: the machine is an Athlon64 3500, and the mobo is an Asus A8V Deluxe Rev 2.0.
