Gleb, > Guess 1: You've got PC UARTs and > drivers/char/serial.c > Guess 2: TAB TAB in bash causes the oops too. > Guess 3: You didn't change famous beep function in > the driver. Correct on all 3 counts. Thanks for pointing the way. Also thanks to Pete Popov and James Simmons. In particular to James for telling me to look at vt.c, functions kd_nosound and _kd_mksound. I changed the ifdef to be aware of my board and now the problem is solved. To All, I am grateful that my problem was solved quickly. But before I posted to the list I did a search on "Backspace oops linux", "Backspace crash linux" and a few other combinations to see if this was possibly a known problem. But turned nothing up. Is there any other list / repository I should be looking at to pick up on bugs like this ? Any tips / info would be greatly appreciated.
