WebI/O’s will fail, returning a value of 0xff on read, and writes will be dropped. If more than EEH_MAX_FAILS I/O’s are attempted to a frozen adapter, EEH assumes that the device driver has gone into an infinite loop and prints an error to syslog. A reboot is then required to get the device working again. 7.1.3. STEP 2: MMIO Enabled ¶
