I have experienced somewhat similar. In my case errors are not always reproducible and generally manifest in late stages of rc2.d (gdm). I managed to get some logs off one of the crashes that was less debilitating.
PS: Not sure if it is relevant but the following sysctl settings are in place: sysctl $quiet -w vm.dirty_background_ratio=0 sysctl $quiet -w vm.dirty_ratio=0 sysctl $quiet -w vm.dirty_expire_centisecs=1 sysctl $quiet -w vm.dirty_writeback_centisecs=1 http://bazaar.launchpad.net/~ubuntu- installer/lupin/hardy/annotate/evan.dandrea%40canonical.com-20080407154533-rztovcdf8foxctkt?file_id=lupinsysctl-20070830094942-u4sn2uojcan8bqi7-1 ** Attachment added: "dmesg" http://launchpadlibrarian.net/13263740/dmesg -- wubi install unusable - Buffer I/O error on device loop0 https://bugs.launchpad.net/bugs/204133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
