The id on the chips is 6, so i guess 60 ns. Your suggestion was really
fascinating. I have downgraded the memory timing from 60 to 70 ns and now
after 1:15 hour of stress-test with kernel compilation (make -j 10),
equivalent to 7 compilations, I have had just two (2):

gcc: Internal compiler error: program cc1 got fatal signal 7

Signal 7 ? What is this ?

Okay okay, no more SIGSEGV (signal 11) and the memory problem seems to be
gone, but this is SIGBUS. Why ? May be an out of memory condition ?

Just now another error showed up in the compilation:

audio.c: In function `audio_select':
audio.c:479: structure has no member named `flags'
audio.c:488: structure has no member named `flags'

but for sure the structure have a member named flags. Seems that the
compiler have chocked somewhere, may be something related with the
conditional compilation ?

Mah !
