Helge,

Sorry I don't understand: where do you read that I switch on serial mux?

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,
