Hi, while trying to run an ASA1000V appliance I found that registers 0x09 and 0x3c-3f are read during boot up. Which currently results in an exit(1). The appliance uses an quite ancient 2.6.29.6 Linux kernel. These registers are mainly for diag and debug purposes so I came up with the following patch. The system works with the following patch, but I wonder if this is a correct workaround:
