    Both warnings occurred when the kernel was tearing down large amounts of
    pagecache via invalidate_inode_pages(). One instances was a blockdev
    (probably the final close on the dvd) and the other was a regular file
    (perhaps a large dvd image?)

    The CPU is slow: 500MHz pIII. How much memory does it have?

    So the kernel was doing a lot of work, on a slow CPU. Perhaps that simply
    exceeded the softlockup timeout. If that's true then the machine should
    have recovered. Once it did, and once it didn't. I don't know why it
