Hello, I'm still trying to boot 3.x on the fuloong2f. I've tracked down my troubles to one config option. if I set VGA_CONSOLE=y, the kernel hangs like the attachment named bootcrossS1_fail.txt (serial log).
If I disable VGA_CONSOLE at build time, all builds fine. But I loose the serial console at some point. And of course the screen does not show anything at all until mingetty or slim starts. See the serial log in bootcrossS1_good.txt. I also noticed that 2.6.36 labels my serial port "ttyS0 at 0x2f8". And 3.x labels my serial port at "ttyS1 at 0x3f8": [ 7.399402] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled [ 7.427931] serial8250.0: ttyS1 at I/O 0x3f8 (irq = 4) is a 16550A So a series of questions come now: Why the serial port changed? Why I can't have VGA console? Why I don't see anything in ttyS1 after "[ 7.434094] console [ttyS1] enabled, bootconsole disabled" ? 'guddu_' at irc at #mipslinux thinks that the PCI is getting reset/reconfigured at boot, and it should not. I've no idea what causes that - I'm using little over the lemote2f defconfig. I also attach the '.config' for the 'good boot'. The failed boot simply has "VGA_CONSOLE" enabled over the 'good config'.
