By now, t0 register restored value is overwritten by mepc and mstatus values prior to returning from ISR. Fixed by restoring mstatus and mepc registers before restoring the caller-saved registers. As t0 is a temporary register within the riscv ABI, this issue was unnoticed for most applications, except for computation intensive apps, like crypto tests.
