ST REGS is intended to show you the regs at time of error. It's pretty unusual to want to display the regs at the time of the SVC Dump.
If it is showing 0's then in all likelihood the regs at time of error are not available. Perhaps you are taking a dump out of "mainline" rather than out of a recovery routine. Time of error regs are gotten (in the usual case) from the RTM control structures (whether RTM 1 work area, RTM 2 work area, or SDWA). But those do not exist for a dump out of mainline. As to why there was no WLIC of 00020033 n the RBs for your task it's probably related to the fact that you asked for an asynchronous dump (and would have gotten back RC=4) by your use of ASIDLST. Usually you would want to specify an ECB and code "IF returncode < 8 then WAIT...". That can help make sure all the data in your space is still present when the dump processing gets around to capturing it. I'm not sure why the non-dispatchability settings wouldn't have captured the TCBs/RBs in any case, but it all starts with the asynchronous dump.
