Er. Suddenly i can see the "abcd" "1234" message in the good log too.
Sorry for the confusion.
Just to make it clear:
Was this kernel loaded from the very same USB stick which it then cannot
inquire properly and in some cases cannot read from ?

This does not match the complaint in the web to which Kent pointed us
The one by your machine is quite clear. The storage device with the
ISO filesystem cannot be found by the kernel.
In Kent's case it seems rather that some particular file cannot be
read from the already found storage device.

If the kernel was loaded by the bootloader from that USB stick, then
the subsequent failures in the kernel run could be caused by some bad
state of the USB stick when the bootloader starts the kernel.
If booting was done via EFI (and not Legacy BIOS mode) then we could
ask at email@example.com, whether the problem is known in any way.
(With BIOS mode we'd need to go to quite dead firstname.lastname@example.org )
How does the stick behave if you plug it into a running GNU/Linux system ?
Any problem messages in the log ? Is it usable as storage device ?
Have a nice day :)
