Looks like a pci/acpi-issue with your toshiba. the kernel can't find a useable irq for the yenta bridge. sometimes you can fix this withbios-entries, but i don't know the 2100. does the 2100 has a phoenix or a toshiba bios? If acpi is enabled on your lappi try to switch it off. If it's disabled try to enable it. use a kernel command line like acpi=off at the bootprompt: linux acpi=off However, acpi is quite useful for laptops.
Another boot option (besides acpi=off) would be acpi=noirq which should leave acpi usable while freeing up an irp.
