New submission from Charles A. Hewson <cahewson at eskimo.com>:
Hi all,
I am working from grml32_testing-20120106 as issue 1126 is fixed there.
Background steps on 32 bit box:
1 create vfat usb stick mkdiskimage -4 /dev/fd0 0 64 32.
2 add dos label with dosfslabel.
3 reboot grml , usb shows in blkid and /mnt/live-rw.
4 copy /live/live-snapshot... to /mnt/live-rw per on screen instructions
from live-snapshot.
5 unmounted /mnt/live-rw and rebooted selection persistent from grml
menu.
6 cpio.gz has size but everything in /root and /home/grml either was not
uncompressed or was overlaid later in boot sequence.
7 added test files to /root and /home/grml, re-did snapshot and 4-6 above.
8 added file live.persistent to /mnt/live-rw and re-did 4-6 above.
9 rebooted and selected debug from grml menu. did tab and added persistent
to cmdline. kernel panic in live-bottom and machine locked up. reset
box.
On win 7 box with current virtualBox:
1 took usb and, created virtual machine similar to 32 bit box, recreated
problem to gather attached files.
2 on this box also attempted by adding "debug=1 log" to persistent menu
line so am confident it is not typing error.
Thanks,
Charles
