When I connect it to a laptop (with only one serial connector) I loose characters of the boot loader output, sometimes I see its complete prompt (boot>) somtimes only half of it, and the same for other output. Any ideas where to start looking, what could be wrong? I _think_ that in the past consolefs worked OK on the same laptop (but maybe I changed kernels in the mean time). Thanks, Axel. --upas-eqscoczfhcetwbnnipoocxufma--
