The sticks I have with SD cards have started to fail on the older computers
at school (after working ok for 2 weeks of lessons). But they still work
fine on my newer Dell mini inspiron. This is a very consistent pattern. I
have 8 sticks with SD cards and 6 have failed on older computers but all of
those 6 still work on the Dell mini inspiron.
They start to boot, the xo icon appears and dots but not icons appear in the
circle. This screen hangs for a while and then exits to a black screen with
Warning: cannot find root file system
Create symlink /dev/root and then exit this shell to continue the boot
bash: no job control in this shell
bash - 4.0#
My other sticks are a mixture of Kingstons and Laser and none of these have
Let me know if you want more detail such as answers to all of the above
