We have a bunch of 501s at a gov account that require CAC/PIV and the AU211. We have followed the install instructions to the letter, but about 75% of the MFPs that the firmware is installed on experiance a control panel lock up anywhere between 5 and 30 min after intial use. The user can log in (swipe card) the MFP will authenticate and user has all defined permission, test print/scan etc..but after 5 to 30 min, control panel locks, MFP will be shut down and will not re-boot past KM Splash screen. We know this is an indication of a corrupt CF card..Go through the process of reflashing MFP from recovery, ver 11, 13, ..up through latest..test MFP and all seems fine..Install CAC/PIV firmware, loadable drivers, AU and start testing..Cycle repeats again after the same time period.. We have tried new CF card, new OACB, with no success...We pulled the CF card from a working MFP and got the same results. Seems that if it is going to work, it works flawlessly, if it's going to fail, then we get the lock up in the usual time frame...Thought it might be firmware/processor (tsunami related), but this only applies to 423/C360..Any thoughts?
