The problem is not only in -mmX, it shows in the -bk series as well. The mmap() problem I am experiencing seems to have been introduced between 2.6.9-rc2-bk1 and 2.6.9-rc2-bk2. This somewhat narrows the research field. I still don't know how to investigate the problem any further. Suggestions welcome. Thanks. -- Jean Delvare http://khali.linux-fr.org/
