FIXES:
Alan Cox: Removed the 'Unexpected interrupt' bug.
Michael Meskes: Upgraded to Donald Becker's version 1.07.
- Alan Cox: Increased the eeprom delay. Regardless of
+ Alan Cox: Increased the eeprom delay. Regardless of
what the docs say some people definitely
get problems with lower (but in card spec)
delays
v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org>
