After a software upgrade that includes an LCD firmware update, the LCD touch panel may remain stuck reporting an error indefinitely / for longer than 30 minutes: Firmware update in Progress may take up to 30 minutes.
The system is functional, but the LCD displays the firmware update screen indefinitely. The LCD cannot be used while it is frozen on the firmware update warning screen.
This issue occurs when all of the following conditions are met: -- You have one of the following BIG-IP platforms: * i850 * i2x00 * i4x00 * i5x00 * i7x00 * i10x00 * i11x00 * i15x00 * HRC-i2x00 * HRC-i5x00 * HRC-i10x00 -- You perform a software upgrade that updates the firmware on the LCD touch panel, e.g. upgrading from BIG-IP v13.1.x to BIG-IP v14.1.x or newer.
Important: Before attempting this workaround, check that there are no indications the system is still performing a firmware update (such as a terminal prompt), and that the following messages can be found in /var/log/ltm after the most recent boot: notice chmand[6302]: 012a0005:5: firmware update succeeded. notice chmand[6302]: 012a0005:5: Firmware check finished. These messages indicates that the firmware update has finished, and the LCD is displaying the warning screen in error, so it is safe to perform the workaround. Reboot the BIG-IP system to return the LCD to normal operation. After a reboot of the BIG-IP operating system, the LCD touch panel should be responsive.
