What devices do you have plugged in? I can't boot up my computer with a flash card inserted in the slot. I can insert it afterwards.
You might try disconnecting unneeded devices such as external drives or flash devices and see if the problem persists.
Look at the output of dmesg or boot.log to see when the first indication of a problem is. Is is associated with loading a particular kernel module?
Look in the text file kernel-parameters.txt in the kernel source. There are several noacpi options that offer more granularity.
What is the make of your mobo? Does google turn up similar messages for that motherboard?
Try a different kernel version.
Look at "grep 'irq=127' /etc/modprobe.conf" and "lspci -v | grep 'IRQ 127'"

It would entail recompiling your kernel enabling debugging for usb and file system access.
I was hoping the modinfo would show possible interupts for a device.
