10 columns of two digits

I must have flipped a switch inadvertently when compiling the kernel last time, which now causes 10 columns of two digits to appear periodically while booting. The columns come and go throughout the text appearing on the terminal. Does anyone know what might have done that? I would like to prevent the appearance of these columns if possible.

Some example? Screenshot/photo?

When I look at output from dmesg, I see numerous instances like the following, which I believe are made in relation to the 10 columns of hex digits I see appearing while booting:

Status code 0; transferred 4096/4096
-- transfer complete
Bulk data transfer result 0x0
Attempting to get CSW...
xfer 13 bytes

etc, etc....ad infinitum...

Sounds like something is going haywire on usb-storage.
Will it do the same with all usb devices unplugged?

It seems that you have event debugging either compiled in or loaded as module (evbug).

Please post output of: lsmod and grep INPUT_EVBUG your_kernel_config.

Hint: your_kernel_config may be eg. /usr/src/linux/.config or try directly from /proc (if enabled): gunzip < /proc/config.gz | grep INPUT_EVBUG

Since I will be AFK for over a week I suggest already - if above commands will show that either

module is loaded and shown in lsmod (and in config =m)
evbug is compiled into kernel (=y in config)

in first case unload it and if it helps blacklist, in second case - recompile kernel removing this feature.

Good call, smerf. It worked. Thanks for taking the time to follow up. You made a new friend.
