It's a bit old (2.2.12), > but it works. Unfortunately, it doesn't work. BootX 1.2.2 shows up only one penguin, and I get the same /proc/cpuinfo. I realized that I have this oddity in dmesg : Entering SMP Mode... Processor 1 is stuck. On 2.2.16 it's the same (dmesg from the begining) : device tree used 31392 bytes Total memory = 64MB; using 256kB for hash table (at c0240000) Linux version 2.2.16 (root@pm9500) (gcc version 2.95.2 20000313 (Debian GNU/Linux)) #2 SMP Mon Jun 12 16:59:05 CEST 2000 PCI bus 0 controlled by bandit at f2000000 Cache coherency enabled for bandit/PSX at f2000000 PCI bus 1 controlled by bandit at f4000000 Cache coherency enabled for bandit/PSX at f4000000 System has 32 possible interrupts via_calibrate_decr: decrementer_count = 112500 (675003 ticks) Console: colour dummy device 80x25 Calibrating delay loop... 358.81 BogoMIPS Memory: 62364k available (1228k kernel code, 1848k data, 96k init) [c0000000,c40 00000] Dentry hash table entries: 8192 (order 4, 64k) Buffer cache hash table entries: 65536 (order 6, 256k) Page cache hash table entries: 16384 (order 4, 64k) POSIX conformance testing by UNIFIX Entering SMP Mode... Processor 1 is stuck. <-------------------- PCI: Probing PCI hardware... It sounds like the second processor cannot be correctly started... I tried with an older bootX (1.1.3) it's the same. For now, I can't quik, I think Darwin messes up quik (it's installed on a partition before linux). The cards work well under MacOS, distributed.net client makes a full use of both processors (which brings the 9500 a bit higher than a G3@333, but still 3,5 times lower than a G4@450..., always accordingto dnet's client) Any though about this ? Any way to debug ?? Thanks, GoM ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
