Last update for today, promise :-)<br><br>On a fresh install of os23 on any of my XO 1.0's, (without moving the .ko driver) with a VGA adapter , doing this first time try booting using 'boot' from OFW, the system will most often hang on the set localhost line right after the [13.xxxxxxx] 'Allocated 8 output buffers' USB line. If it hangs right here, if I now unplug the VGA adapter it continues to boot. <br>
<br> If instead, the console lines on an OFW boot continue through the [14.xxxxx] and hang on the diisplay of libertas lines, then removing the VGA adapter does not cause the boot to continue. It sits there unhappily idle.<br>
<br>So bottom line ruight now is that the 'workaround' for the intermittent problem listed as in the ticket does not carry forward to 11.2. I cannot get it to give VGA outputon an XO 1.0 on build 11.2, at all. External power is in, and the VGA display is ready for all the above tests.<br>
<br>Awaiting more orders.<br><br>Cheers<br><br>KG<br><br><br><br><div class="gmail_quote">On Wed, Jun 22, 2011 at 7:39 AM, Kevin Gordon <span dir="ltr"><<a href="mailto:kgordon420@gmail.com">kgordon420@gmail.com</a>></span> wrote:<br>

Boot without USBVGA connector attached. Go to a root terminal and move<br>
sisusbvga.ko to /root:<br>
# mv /lib/modules/*/kernel/drivers/usb/misc/sisusbvga/sisusbvga.ko /root<br>
<br>
Power off the system, connect USBVGA, boot. It should boot<br>
successfully, but without any VGA output. Press ctrl+alt+f2 to get to<br>
a root terminal, and stop X/sugar with:<br>
# stop prefdm<br>
<br>
Now load the sisusbvga driver manually and see if it hangs:<br>
# insmod /root/sisusbvga.ko<br>
<br>
Wait a few seconds, see if the system is hung or if you can still type<br>
on the console.<br>
<br>
If you can still type, unload the module:<br>
# rmmod sisusbvga<br>
<br>
and now try loading/unloading a few more times with a few seconds<br>
pause between each step.<br>
# insmod /root/sisusbvga.ko<br>
...<br>
# rmmod sisusbvga<br>
...<br>
# insmod /root/sisusbvga.ko<br>
...<br>
# rmmod sisusbvga<br>
...<br>
etc<br>
<br>
The idea is to find out whether the system hang is caused by the<br>
loading of sisusbvga. It might not hang first time, may require a few<br>
attempts, hence the repeated loading.<br>
<br>
Thanks,<br>
