The issue was that the service routine was sometimes returning with the wrong flags set in the MSR. In this case, EIP bit was set while returning to User Mode which is an illegal combination since exceptions are always handled in privileged mode. In order for MicroBlaze to take an interrupt, the MSR must have IE=1, BIP=0 and EIP=0.
