dissable interrupts with CPSR

Hi,
this regards the ARM 7 core.
In the CPSR register I can set the "I bit" to dissable the "IRQ interrupts" But which all interrupts does this mean, and which interrupts will remain active?
For example at the Cortex M3 there are high priority exceptions like
- BusFaultException
- HardFaultException
Does the ARM7 also have exceptions like this that is not covered by the "I bit" ?
