Ahh, that's embarrasing. My fault. I was compiling LLVM 3.1 on a 4G machine, while browsing with many many tabs. When the link stage starts, it consumes lots of RAM and forces the system to swap. I confirmed the RAM thrashing from a remote top. I didn't expect compiling LLVM to use that much RAM.
That's where my mouse movement becomes sluggish and finally freezes. Flash player either crashes or freezes and cosumes 100% CPU during swapping. Killing flash is really not the action which restores the system. Only after ld fails, my system becomes responsive again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
