Hmm.. the logs of the current boot should be available? Anyway, as you don't have logs to get a clue on what's happening, I think the only way is to check whether the module was actually loaded.
List modules, check if hpsa is loaded:
esxcfg-module -l / vmkload_mod -l
See if module can be loaded manually:
esxcfg-module <module name> / vmkload_mod <module name>
Disable specified module, if you are certain about the problematic module:
esxcfg-module -d <module name>
