Then building your fat config with -rc3, 'ps' hangs > on qemu for almost 30 seconds and then at last produces a broken output Let me guess - you have either a serial console or something like that and you're running these commands over said serial console? Or you have console directed to both a serial port and the VT and you're capturing this off the VT using gpm. Either way, "serial8250: too much work for irq4" is a printk which will be displayed by the kernel when it's unable to clear down work for the serial port within 256 loops or so of the interrupt handler; it's a protection against the box locking up. It not actually contained in any of the files. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
