reason for delay in arch/x86/kernel/traps.c::io_check_error()?

[Chris Friesen]

Hi all,

I was just wondering about the basis for the delay in io_check_error(). 
 The ICH7 manual doesn't have any mention of a delay being required 
here--is it necessary for other hardware, something not mentioned in the 
manual, or just an accident?

Thanks,

Chris
