Neither linux-4.3-rc1 nor linux-4.3-rc2 boot properly on my Intel Core 2 E6600---lost one of two cores. Google search found one other person reporting linux-4.3-rc1 also booting with only one core. His Intel CPU was a year or two newer than mine.
linux-4.3-rc1 showed more problems during boot including something about mtrr and another thing I forgot. The mtrr and ? are not showing in -rc2. I had to photograph early boot to capture boot change from a normal working kernel. (My Fedora is 14, gcc 4.5.1).
(start insert 3 screen photos transcribed) AMIBIOS ASUS P5B-Deluxe ACPI BIOS Revision 1238 CPU : Intel Core 2 CPU 6600 @ 2.4GHz -- Booting Fedora (4.3.0-rc2) in 5 seconds... -- early console in decompress_kernel (next 5 lines never appear with 4.2.1 and older kernels) input_data: 0x000000000181026e input_len: 0x00000000003c93c3 output: 0x0000000001000000 output_len: 0x0000000000bc7870 run_size: 0x0000000000c72000
Decompressing Linux... Parsing ELF... done. Booting the kernel. smpboot: do_boot_cpu failed(-1) to wakeup CPU#1 (end insert)
but continues to bootup and works with one CPU.
/proc/cpuinfo shows only one of two CPU cores: siblings : 1 cpu cores : 1 (both should be : 2 )
With -rc2, /proc/mtrr is same as a working kernel (-rc1?): reg00: base=0x0d0000000 ( 3328MB), size= 256MB, count=1: uncachable reg01: base=0x0e0000000 ( 3584MB), size= 512MB, count=1: uncachable reg02: base=0x000000000 ( 0MB), size= 8192MB, count=1: write-back
How can I fix this?
Thanks, Don
