I have, in the past, produced working LFS systems on P3 and Pentium D hardware. For three months I have tried to compile LFS/CLFS systemd on a G4500 Pentium skylake system. I have concluded after 13 attempts that the "skylake prime number hardware bug" makes it impossible.
My new hardware is well behaved as long as Xorg is used, not wayland. All distros tried work well as long as a more current kernel is used. Tried CLFS the first eleven times (most to completion) on Debian-based, Ubuntu, openSUSE and Arch-based. Switched to LFS with the same results: Kernel messages regularly popping-up everywhere and an ethernet interface not discovered by dbus. My last attempt using 7.9 RC2 with openSUSE Leap failed testing in Chapter 6.14, GMP-6.1.0. I ignored the failed tests last time through and produced the same bad results as with CLFS. The output of the failure is: make check-TESTS make[4]: Entering directory '/sources/gmp-6.1.0/tests/mpn' make[5]: Entering directory '/sources/gmp-6.1.0/tests/mpn' PASS: t-asmtype PASS: t-aors_1 PASS: t-divrem_1 PASS: t-mod_1 ../../test-driver: line 107: 8187 Illegal instruction "$@" > $log_file 2>&1 FAIL: t-fat PASS: t-get_d PASS: t-instrument PASS: t-iord_u PASS: t-mp_bases PASS: t-perfsqr PASS: t-scan PASS: logic ../../test-driver: line 107: 8379 Illegal instruction "$@" > $log_file 2>&1 FAIL: t-toom22 ../../test-driver: line 107: 8403 Illegal instruction "$@" > $log_file 2>&1 FAIL: t-toom32 ../../test-driver: line 107: 8427 Illegal instruction "$@" > $log_file 2>&1 ...etc..etc Is this a failed internal cpu instuction? -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
