There was an issue with this when we switched to CCS 6. We had to change the code at the start of the software interrupt to this:

//make sure interrupts are disabled

asm(" STMFD SP!, {R4} "); //Store R4

asm(" MRS r4, cpsr "); // get psr

asm(" ORR r4, r4, #0xc0 "); // set interrupt disables

asm(" MSR cpsr_cf, r4"); // restore psr

asm(" LDMFD SP!, {R4} "); //Restore R4

I'd check and see if that is there, or if necessary, change it, and try again.
