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
