Thank you Bret, that was very helpful. I found the following corrupted files on a newly installed Tribe 5. / is XFS and /boot is Reiser3.
debsums: checksum mismatch firefox file /usr/lib/firefox/components/libuconv.so debsums: checksum mismatch firefox file /usr/lib/firefox/components/libgklayout.so debsums: checksum mismatch gnome-utils file /usr/share/gnome/help/baobab/fr/figures/baobab_fullscan.png debsums: checksum mismatch libc6 file /usr/lib/gconv/libCNS.so debsums: checksum mismatch ttf-dejavu-extra file /usr/share/fonts/truetype/ttf-dejavu/DejaVuSansCondensed.ttf And on another system, all Reiser3 I found: [EMAIL PROTECTED]:~# cat debsums.txt|grep mismatch|cut -d ' ' -f4|uniq|wc -l 140!!! So I quickly reinstalled with: debsums -s &> debsums.txt cat debsums.txt|grep mismatch|cut -d ' ' -f4|uniq|xargs apt-get -y --force-yes --reinstall install And everything seems to be OK now. Gutsy is very crashy with the desktop effects enabled so it might explain the corruption from all the rebooting. I thought Reiser and XFS were supposed to protect me from that so there might be a bug in the kernel. I have also disabled the write cache on my drives with hdparm -W0 /dev/sda as recommended by the SGI folks to see if it helps . My /etc/hdparm.conf now contains the following additions. /dev/sda { write_cache = off } /dev/sdb { write_cache = off } -- Bus error when running Firefox or Epiphany https://bugs.launchpad.net/bugs/133786 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
