controllers. New behaviour is that if the standard method fails, try
to recalibrate the drive. Success means the drive exists. patch by
hpeyerl@novatel.cuc.ab.ca (who owns several of these historical
artifacts)
This patch adds the symbol names to icu.s that vmstat expects
the interrupt counters to be called. It also adds code to config
so that the names of the interrupts are written at the end of vectors.s
so vmstat can report real device names. It also cleans up and enables
the logging of stray interrupts. The counters for false interrupts
are added but the fix for them is not (the fix I have is not done
very good.) A false interrupt is when a device asserts it's interrupt
signal, then removes it before the 8259 can latch it. This is the number
one cause of stray IRQ7's and IRQ15's.
Additional device probe information is now printed. This includes
ending I/O address (many drivers do not return the correct value from a
probe this still needs to be fixed), memory address and size, driver
flags passed in by config.
