Hi, somewhere between 9.0-amd64 r216351 and r216738, I've noticed some userland weirdness. Symptoms are: - pseudo-random number generator not starting, preventing ssh(d) from working - fonts in X.org (xfce4) missing or replaced - mouse only working when hald is running I don't know if the above symptoms are somehow related, or what causes them. The kernel is GENERIC without (u)lpt and umass and with these modules loaded: fdescfs.ko if_iwn.ko snd_hda.ko sound.ko umass.ko iwn5000fw.ko nvidia.ko (256.53) linux.ko cuse4bsd.ko atapicam.ko linprocfs.ko Kernel and world are compiled with FreeBSD clang version 2.8 (tags/RELEASE_28 115870) 20101007 Reverting to r216351 (kernel, world, mergemaster) brought things back to normal. I can do a binary search if desired. Did someone else also see this? Happy 2011, Rene _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
On Fri, 31 Dec 2010 22:35:05 +0100 Try backing out rtld down to version prior to this commit http://svn.freebsd.org/changeset/base/216695 . There is an issue with rtld's use of SSE on amd64 which will be fixed soon. -- Alexander Kabaev
i've seen this issue, too. i did a complete buildworld/installword using gcc as compiler and after that everything worked fine again. so clang seems to be causing the problem. simply back out any clang entries in src.conf and buildworld/installworld should fix your issue. please also see the thread "issue with clang and CPUTYPE native" on freebsd-toolchain, which seems to also be caused by the rtld issue. cheers. -- a13x _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
i tried adding the following to CFLAGS to prevent clang from using any SSE* instructions, but it seems that doesn't work: CFLAGS=-mno-sse -mno-sse2 -mno-sse3 -mno-3dnow -mno-ssse3 returned: fatal error: error in backend: SSE register return with SSE disabled *** Error code 1 in lib/libcompiler_rt. cheers. -- a13x _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"

Backing out src/libexec/rtld-elf to r216694 solved it for now :) Rene -- http://www.rene-ladan.nl/ GPG fingerprint = ADBC ECCD EB5F A6B4 549F 600D 8C9E 647A E564 2BFC (subkeys.pgp.net) _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
Yeap, i had the same issue two days ago. I was getting errors from ssh (PRNG is not seeded), kdm4 could not start etc. I did a csup after ten minutes and recompiled with gcc.

Maybe, but then something is still wrong, as the version I reported is Rene _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
A happy new yaer René, At Fri, 31 Dec 2010 22:35:05 +0100, I suppose you've been hit by rtld bug between r216695[*1] and r216728[*2]. It broke certain kind of dynamic linking so weird things might happen. Like unexpected font selected, flash movie malfunctioning in firefox, some port compilation failure[*3], etc, etc. They all have happened on me and already gone. Hope this helps. -- kuro [*1] r216695: http://docs.FreeBSD.org/cgi/mid.cgi?201012250851.oBP8pLLm017014 [*2] r216728: http://docs.FreeBSD.org/cgi/mid.cgi?201012270030.oBR0UTq9004790 [*3] "problem with port gobject-introspection on 9.0-CURRENT" http://docs.FreeBSD.org/cgi/mid.cgi?alpine.LRH.2.02.1012261329550.8533 and http://docs.FreeBSD.org/cgi/mid.cgi?alpine.LRH.2.02.1012282053100.28301 (He is my hero.) _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
