PROBLEM SUMMARY: The crash occurs during a narrow window where the DLUR-DLUS pipe fails during the activation of a DLUR internal PU. During this window, the TG control vectors are sent in a TDU with a 12C2 vector; this fails, and is not correctly handled to reset the control block, resulting in an attempt to access a NULL pointer and causing the crash.
Problem conclusion
Code has been corrected to properly handle this error case.
Temporary fix
