 |
|
Finalmente o meu 133 já instalou 
Agora é o meu amd duron que me está dar problemas
Instalei o sistema de stage 3 e até agora tudo tinho corrido bem
De repende começam a vir os seg faults
Seg fault a compilar
| Code: |
sh.hist.c: In function `dohist1':
sh.hist.c:312: internal error: Segmentation fault
|
Seg fault do kernel...
já nem consigo recompilar o kernel com novas flags....
Será das flags com que compilei o sistema??
estava a usar march=k6 -O3 -pipe -fomit-pointer
estou a tentar sacar o gcc de novo para o compilar com as flags :
CFLAGS="-mcpu=k6 -O3"
Já alguem aqui teve um problema semelhante???

Já agora qual é modelo do duron? Existem durons baseados em 2 ( ou até 3 core's se bem me lembro ), e a utilização da opção errada resulta em problemas como o teu.
| Quote: | -mcpu=cpu-type
Tune to cpu-type everything applicable about the generated code, except for the ABI and the set of available instructions. The choices for cpu-type are i386, i486, i586, i686, pentium, pentium-mmx, pentiumpro, pentium2, pentium3, pentium4, k6, k6-2, k6-3, athlon, athlon-tbird, athlon-4, athlon-xp, athlon-mp, winchip-c6, winchip2 and c3.
While picking a specific cpu-type will schedule things appropriately for that particular chip, the compiler will not generate any code that does not run on the i386 without the -march=cpu-type option being used. i586 is equivalent to pentium and i686 is equivalent to pentiumpro. k6 and athlon are the AMD chips as opposed to the Intel ones.
-march=cpu-type
Generate instructions for the machine type cpu-type. The choices for cpu-type are the same as for -mcpu. Moreover, specifying -march=cpu-type implies -mcpu=cpu-type. |
Espero que isto ajude em alguma coisa, aconcelho-te a ver o topico das https://forums.gentoo.org/viewtopic.php?t=56951 e vê o post do RoadRunner.

O memtest86 ajudou
Afinal era uma DRAM que estava a dar erros |

já tive problemas de memoria aconselho a usar na tua configuraçao do kernel
| Code: |
Machine Check Exception OFF (disable)
|
para n teres kernel panics
e em caso de compilar mal conselho a usar nas CFLAGS
| Code: |
CFLAGS="march=xxx ou mcpu=xxx -O2 -pipe"
