Thanks Willy, So i just compile a new Kernel with options we have talking about... And it's freeze, nothing to the console...
So i need to find the way to enable the Level-Triggered Interrupts in the kernel to the right IRQ address... I read the thread... but i can't find the thing to change in kernel source or kernel configuration. Or perhaps i enable to many option in "Device Drivers --->" "Character devices-->" "Serial drivers --->" <*> 8250/16550 and compatible serial support x x x x [*] Console on 8250/16550 and compatible serial port x x x x (4) Maximum number of non-legacy 8250/16550 serial ports x x x x [*] Extended 8250/16550 serial driver options x x x x [*] Support more than 4 legacy serial ports x x x x [*] Support for sharing serial interrupts x x x x [ ] Autodetect IRQ on standard ports (unsafe) x x x x [*] Support special multiport boards x x x x [*] Support RSA serial ports Try autodetect IRQ ? I'll try to learn more about edge/level irq sharing...
