The problem is here: > grep MODULE * linux_sysvec.c:MODULE_VERSION(linux, 1); linux_sysvec.c:MODULE_DEPEND(linux, osf1, 1, 1, 1); linux_sysvec.c:MODULE_DEPEND(linux, sysvmsg, 1, 1, 1); linux_sysvec.c:MODULE_DEPEND(linux, sysvsem, 1, 1, 1); linux_sysvec.c:MODULE_DEPEND(linux, sysvshm, 1, 1, 1); linux_sysvec.c:DECLARE_MODULE(linuxelf, linux_elf_mod, SI_SUB_EXEC, SI_ORDER_ANY); All the dependencies are recorded for the non-existent linux module. In actuality, on Alpha there is a linuxelf module, and on i386 there are linuxelf and linuxaout modules. I'm trying to think about the best way to go about fixing this. Well, I have an untested patch at http://www.FreeBSD.org/~jhb/patches/linux.patch that might fix this. FWIW, the dependency of linux compat on the SYSV modules was broken on both i386 and alpha for the same reason. Use 'patch -p6' to apply this patch btw. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
