<4>pcmcia: request for exclusive IRQ could not be fulfilled.
<4>pcmcia: the driver needs updating to supported shared IRQ lines.
<4>ttyS0: detected caps 00000700 should be 00000100
<6>0.0: ttyS0 at I/O 0xc48203f8 (irq = 40) is a 16C950/954

I thought it conflicts with serial_console on ttyS0 but disabling the spawn in
.init didn't help.

Pls check kernel's .config (irq sharing options).
