Ok, 2.6.8.1-mm2 minus dev-mem-restriction-patch.patch fixes the "cannot allocate memory" problem. With this kernel I still get the --8<----------------------------------------------------------------------- vmmon: Your kernel is br0ken. get_user_pages(current, current->mm, b7dd1000, 1, 1, 0, &page, NULL) returned -14. vmmon: I'll try accessing page tables directly, but you should know that your vmmon: kernel is br0ken and you should uninstall all additional patches you vmmon: have installed! vmmon: FYI, copy_from_user(b7dd1000) returns 0 (if not 0 maybe your kernel is not br0ken) --8<----------------------------------------------------------------------- warning, but vmware appears to work now (well apart from altgr not working, but that has been broken since 2.4 -> 2.6 transition.) I'm still not 100% which of the patches causes that get_user_pages() warning. -- v -- v@iki.fi
