An update for the Snapdragon Flight image that provides DSPAL support is available with the critical pthread_cond_timedwait fix. Please download from http://support.intrinsyc.com/attachments/download/503/Flight_adsp_8074_firmware.zip, extract and copy the contents to /lib/firmware on target and restart the target​.
These fixes will also be included in the next official release from Intrinsyc but this download provides early access to the fix.
