17.6 Rec709 Colorspace Issue on Alternate Inputs
17.6.1 Description

For example, the reference points are shifted, colors are not saturated, or the white is tinged
with a little magenta.
17.6.2 Identification
No error in the logs.
17.6.3 Solution
Install firmware version 4.1.7 and SM version 6.0.15 or higher.
17.7 Filesystem Corruption
17.7.1 Description
The filesystem is corrupted. Symptoms include:
Arborescence is wrong and showing ??? instead of some files/directories.
The KDM or DLM folders in /data lose their symbolic link to /doremi/dlms and
/doremi/kdms and KDMs/DLMs are lost as a result.
17.7.2 Identification
When looking at \doremi\log\kern.log (or \doremi\log\kern.log.x if the issue occurred a while
before the report was taken), you may see these kinds of messages when this issue occurs:
IMS1000 kernel: EXT3-fs error (device md1): ext3_check_descriptors: Block bitmap for group
16 not in group (block 589824)!
IMS1000 kernel: EXT3-fs (md1): error: group descriptors corrupted
Look at drmreport.txt file and search for “ls -laRi /data,” or simply run “ls -la /data” on the unit if
you can access it. When this issue occurs, dlms and kdms folders do not show their symbolic
link to /doremi/dlms and /doremi/kdms, or some folders are missing and showing ??? instead.
