You probably need to change the .config so CONFIG_64BIT is not set. _OR_ use the 64-bit compiler: make -j2 CC=hppa64-gnu-linux-gcc-4.2 > > 2) I'm testing 32-bit kernels. > > indeeed disabling 64 bit support brings the cpu back Ok.

Sorry...that question was really targeting others on parisc-linux list. The diff will some noise in it because 64-bit has to "F-extend" all physical addresses to be 64-bit. (That's not quite the same as sign extension because of some wonkiness in 32->64 bit phys address aliasing.) thank, grant > --- dmesg.txt 2008-04-21 11:19:16.000000000 +0200 > +++ dmesg2.txt 2008-04-21 15:27:46.000000000 +0200 > @@ -1,6 +1,7 @@ > -Linux version 2.6.22-3-parisc64-smp (Debian 2.6.22-6) (maks@xxxxxxxxxx) (gcc version 4.1.3 20071019 (prerelease) (Debian 4.1.2-17)) #2 SMP Mon Nov 12 21:04:20 CET 2007 > +Linux version 2.6.25 (cavok@ska) (gcc version 4.1.3 20080308 (prerelease) (Debian 4.1.2-21)) #8 SMP Mon Apr 21 12:25:50 CES8 > FP[0] enabled: Rev 1 Model 16 > The 64-bit Kernel has started... > +console [ttyB0] enabled > Initialized PDC Console for debugging. > Determining PDC firmware type: System Map. > model 00005d10 00000491 00000000 00000002 77b406fc 100000f0 00000008 000000b2 000000b2 > @@ -8,41 +9,28 @@ > CPUID vers 17 rev 10 (0x0000022a) > capabilities 0x3 > model 9000/785/J5600 > -Memory Ranges: > - 0) Start 0x0000000000000000 End 0x00000000efffffff Size 3840 MB > - 1) Start 0x00000010f0000000 End 0x00000010ffffffff Size 256 MB > -Total Memory: 4096 MB > -initrd: 7fa75000-7ffee77e > -initrd: reserving 3fa75000-3ffee77e (mem_max 100000000) > -On node 0 totalpages: 983040 > - Normal zone: 13440 pages used for memmap > - Normal zone: 0 pages reserved > - Normal zone: 969600 pages, LIFO batch:31 > -On node 1 totalpages: 65536 > - Normal zone: 896 pages used for memmap > - Normal zone: 0 pages reserved > - Normal zone: 64640 pages, LIFO batch:15 > +Total Memory: 3840 MB > LCD display at fffffff0f05d0008,fffffff0f05d0000 registered > SMP: bootstrap CPU ID is 0 > -Built 2 zonelists.
