Hi folks, got a box here which says: [ 4.654361] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled [ 4.660820] 00:06: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A [ 4.668313] printk: legacy console [ttyS0] disabled [ 4.676903] serial 00:06: Runtime PM usage count underflow! [ 4.677175] serial 00:06: disabled [ 4.677264] serial 00:06: unable to assign resources [ 4.677356] serial 00:06: probe with driver serial failed with error -16 [ 4.677923] printk: legacy console [ttyS0] disabled Any suggestions? I'd like to use the serial cable to catch dmesg but somehow the driver doesn't like the chip... Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
