Hey Martin,

Ok, I can confirm that when I busy loop during fiasco init, I can actually see
the character that I typed. So would I have to change the l4ser driver

Hi Martin,
Thanks for checking that. I also see that my build works provided I don't apply a special patch meant for my board (Intel SCC).
The patch essentially only alters the frequency and disables the PIC.

Hi Ramya,
Why did you disable the PIC?
What is your aim with ACPI and why should this lead to a change in the UART
driver?
And what has the serial console to do with ACPI tables?
For me the topics have

something arrived.

Hi Masti,
I just applied your config, replaced drops-rd.rd by ramdisk-x86.rd and everything (command prompt, debugger) runs fine as
