h1susb13 and h1psl0 front end crash from timing errors. New h1ascimc model.

All the h1susb13 models stopped with timing errors this afternoon, followed later by h1psl0's iop model. CER activity was ongoing around this time.

We tried a model restart on h1psl0, which did not work. We rebooted the machine and all started OK.

We tried a reboot of h1susb13, but it got stuck. We then hard-reset the computer via IPMI and all came back OK.

Following the recovery of h1iopsusb13 I untripped the BSC1 and BSC3 SWWDs (the SEI had tripped).

Daniel had a new h1ascimc model to install (no DAQ restart). We stopped h1ascimc, which caused a DAC error on h1iopasc0. So as before, we had to restart all the h1asc0 models to load a new h1ascimc.
