problems with interrupt handler pc386

[Satyaki Mukherjee]

Hello Everybody,
    I am writing a sample application for pc386 BSP that does the
following -
1. Create and start a thread that waits on RTEMS_EVENT_0
2. Register an ISR for IRQ 8 (BSP_RT_TIMER1 as per irq.h)
3. Inside the ISR, signal RTEMS_EVENT_0 so that the thread created comes
   out of wait

Unfortunately, the thread never wakes up. In other words it seems, the
interrupt handler
is never invoked. What could be missing?

Any pointers in this regard would be highly appreciated.

Regards
Satyaki
