Thread: Freezing at boot

  1. #1

    Question Freezing at boot

    I'm trying to use the x86_64 version of openSUSE 11.1.

    During the installation reboot (or any later boot), my laptop (Acer Aspire 5100) freezes entirely with corrupt graphics. The display looks as if the first 100 or so pixels are repeated horizontally and that scanline is repeated, so I just see repeating groups of vertical lines.

    At this point, the small progressbar underneath the "openSUSE" logo has moved maybe 2 pixels. When it freezes, the hang is complete (all I can do is force the laptop off by holding the power button for 5 seconds).

    The odd thing is that it boots normally 99% of the time if I have any USB storage device plugged in. The installation DVD always boots normally.

    I've searched the forums, but not found anything useful yet (probably because the terms mostly lead to booting off USB devices etc). Is there any workaround other than plugging in a USB stick every time I need to boot? It's not that big a deal, but gets especially annoying whenever I forget it.

    Yes. Makes no difference.

    Please boot and press Esc. to get verbose mode. Text will display, try and see what it says, we are looking for error messages.

    Was the usb storage device in anyway connected with the install?

    I've tried this too, there are no error messages that I can see (although I may simply not see it because the same corruption occurs in text mode resulting in grey on black lines rather than light- on dark green). The last thing I can read is a line about acpi and vga. It moves by too fast to see what it is, but doesn't look like an error (I've seen the same line flash by during successful boots). It doesn't get to the normal services initialisation (no green "done" text anywhere in sight). I don't think the root file system has been mounted in writeable mode yet, so it's kinda tough to get a log too.

    No, I've tried reinstalling several times, figuring it might have something to do with USB devices being connected during the installation. It made no difference. It also doesn't matter what storage device I connect. Even an (empty) ATAPI CD-ROM drive using an IDE-to-USB converter cable will allow it to boot.

    I've also flashed the BIOS to the latest version available from the Acer site, but that too made no discernible difference (also tried reinstalling after the BIOS update).

    I haven't tried using something like a USB webcam (there's one built in anyway) nor have I tried the 32bit version, which I may try if I have a lot of time.

    I'm not sure this will help, but it will not do any harm:

    Pause the boot by moving the down arrow, then back up to the default boot. But now press backspace, it should delete any text where you can see VGA=...etc
    Remove all text and now type just the number:
    3
    and hit enter


    at the login type your user name and then password
    now type:
    su
    then the root password


    now type this:
    sax2 -r -m 0=vesa
    (N.B. the 0 is a zero not a letter)
    now reboot: type: reboot


    if you don't get a gui login
    login as user at cli and try this at the cli
    startx

    It never gets to the login prompt without the USB device connected (neither in text nor graphics mode -- I prefer text-only anyway). With it, it boots normally and I get my KDE desktop just fine (or Gnome, on another install attempt).

    Let me correct my earlier statement: it does get to initialising some services, but not far enough to have /var/log/boot.omsg available on a successful boot.

    The last line displayed is one of the following three (it varies, but these lines are very close together in the boot process):
    "ACPI: Video device [VGA] (multi-head: yes rom:no post: no)",
    "rtc0: alarms up to one month" or
    "registered led device: acer-wmi::mail"
    It never gets past that last one on a failed boot. On a successful boot, that line is followed by
    ipw220: Detected geography ZZR (14 802.11bg channels, 0 802.11a channels)

    Please try adding: acpi=off
    to the boot argument - do you know how to do that?

    Yes. And it has no effect. It is also one of the options included in the failsafe boot.

    Oh, and just to be sure: I had memtest86 running overnight and it reported no problems (for weird stuff like this, I generally suspect faulty RAM).
