I noticed that the function mpc52xx_uart_int_rx_chars() does not check the return value of tty_insert_flip_char(). If the system runs out of space (actually, the maximum buffer size used should be limited, in particular on embedded systems!), might this go undetected? This might explain the bigger "chunks", as the '5200's uart has a rather big fifo (512 bytes). >>> >>> That might help, have you tried changing this and seeing if it fixes anything? > > Ummm. Apparently this was a hardware problem. No errors on a 2nd board, and re-soldering the chip on the 1st fixed it there, too. Probably a "cold" soldering. Ah, good, I like the "buggy hardware" type resolutions :) thanks for letting us know. greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
