    SubjectLinux Test Project results on 2.4.10-ac7


    Results from one test run:

    10692 test cases PASS
    12 test cases that FAIL in 2.4.10-ac4 now PASS (personality)
    24 test cases FAIL


    This VFS message displayed on the console about 1 minute into the test:

    These tests, as usual, cause the most noticeable delays in keyboard response. Keystrokes
    are not lost, but I can type several things in vim and it takes a few seconds for them
    to eventually blast on the display. At one point I looked at "top" during one of these
    pauses and saw kupdated and vim with D STAT.

    growfiles -b -e 1 -i 0 -L 120 -u -g 4090 -T 100 -t 408990 -l -C 10 -c 1000 -S 10 -f Lgf02_
    growfiles -b -e 1 -i 0 -L 120 -u -g 5000 -T 100 -t 499990 -l -C 10 -c 1000 -S 10 -f Lgf03_
    growfiles -b -e 1 -i 0 -L 120 -w -u -r 10-5000 -I r -T 10 -l -S 2 -f Lgf04_


    This shows that all of the growfiles tests succeeded:

    Memory
    ------
    Near the end of ltp, this test runs twice:

    Filling up 80% of ram which is 1177360793d bytes
    PASS ... 1177550848 bytes allocated.
    cmdline="mtest01 -p80"

    Both tests succeed at memory allocation. Interestingly, the swpd vmstat column
    stays large after the tests completes:

    Log notes
    ---------
    /var/log/messages file shows:

    Oct 5 23:16:29 rushmore modprobe: modprobe: Can't locate module personality-1

    Repeats 12 times for personalities 1-11 and 221
    Note: 12 of 13 personality tests now PASS

    Oct 5 23:16:48 rushmore modprobe: modprobe: Can't locate module net-pf-0

    I thought the net-pf-0 module might be enabled by CONFIG_RTNETLINK, but
    perhaps it is something else:

    root@rushmore:/usr/src/linux# grep NETLINK .config
    CONFIG_NETLINK=y
    CONFIG_RTNETLINK=y
    CONFIG_NETLINK_DEV=y
    root@rushmore:/usr/src/linux# ls -l /dev/tap0
    crw-r--r-- 1 root root 36, 16 Jul 23 03:28 /dev/tap0
