My goal is to test pdc_console mainly for EARLY_BOOTUP_DEBUG facility (for later b2k 64bit kernel pb). Also afaik otc I have to switch off serial mux (well i say uncheck): drivers/serial/Kconfig [snip] config PDC_CONSOLE bool "PDC software console support" depends on PARISC && !SERIAL_MUX && VT default n [snip]? Thanks in advance for more info, Joel
