CC2510: PM2 and DMA Descriptor

i was trying use PM2 with Radio, 

i want my device to be in PM2 for specific time and after wake up need to do Radio Task, in that i followed the Errata but facing  issues while changing the crystal, and with DMA. 

i pasted my code in active mode but after downloading the code it never wake up from the PM2, although following errata,

void main(void)
{

//halPowerClkMgmtSetMainClkSrc(CRYSTAL);

volatile uint8 storedDescHigh = DMA0CFGH;
volatile uint8 storedDescLow = DMA0CFGL;
volatile int8 temp;
P1SEL &= ~(BIT3 | BIT0);
P1_0 = 1; P1_3 = 1;
P1DIR |= (BIT3 | BIT0);

setup_sleep_interrupt();


Channel = 0x05;
radioConfigure(DataRate, Freq);
while(1){


//=============================== CLOCK SETUP ==============================//

SLEEP &= ~SLEEP_OSC_PD;
while( !(SLEEP & SLEEP_HFRC_S) );
CLKCON = (CLKCON & ~CLKCON_CLKSPD) | CLKCON_OSC | CLKSPD_DIV_2;
while ( !(CLKCON & CLKCON_OSC) ) ;
SLEEP |= SLEEP_OSC_PD;

// Set LS XOSC as the Sleep Timer clock source (CLKCON.OSC32 = 0)
CLKCON &= ~CLKCON_OSC32;

//=================================active-mode==========================================//

halPowerClkMgmtSetMainClkSrc(CRYSTAL);
printf("\n ch:%x",MARCSTATE); //DEVICE STATUS
RFST = STROBE_RX; //sending RX strobe For CCA
while(!(MARCSTATE & 0x0D)); //wait unitll itgoes in Recive mode !
printf("\n after ch:%x",MARCSTATE); //Read MARCSTATE To Check device is in Recieve mode 
printf("\n pkt ch:%x",PKTSTATUS); 
while(!(PKTSTATUS & CCA_FLAG)); //if channel is clear then send the BYTES 
RAD_MODE_TX();
halWait(200);
halWait(100);

storedDescHigh = DMA0CFGH;
storedDescLow = DMA0CFGL;
DMAARM |= (DMAARM_ABORT | DMAARM0);

// Update descriptor with correct source.
dmaDesc[0] = (uint16)&PM2_BUF >> 8;
dmaDesc[1] = (uint16)&PM2_BUF;
// Associate the descriptor with DMA channel 0 and arm the DMA channel
DMA0CFGH = (uint16)&dmaDesc >> 8;
DMA0CFGL = (uint16)&dmaDesc;
DMAARM = DMAARM0;

WORCTRL =0x05;
temp = WORTIME0;
while(temp == WORTIME0);

// Set Sleep Timer Interval
WOREVT1 = EVENT0_HIGH;
WOREVT0 = EVENT0_LOW;

// Make sure HS XOSC is powered down when entering PM{2 - 3} and that
// the flash cache is disabled.
MEMCTR |= MEMCTR_CACHD;
SLEEP = 0x06;

// Enter power mode as described in chapter "Power Management Control"
// in the data sheet. Make sure DMA channel 0 is triggered just before
// setting [PCON.IDLE].
asm("NOP");
asm("NOP");
asm("NOP");
if(SLEEP & 0x03)
{
asm("MOV 0xD7,#0x01"); // DMAREQ = 0x01;
asm("NOP"); // Needed to perfectly align the DMA transfer.
asm("ORL 0x87,#0x01"); // PCON |= 0x01 -- Now in PM2;
asm("NOP"); // First call when awake
}
// End of timing critical code

// Enable Flash Cache.
MEMCTR &= ~MEMCTR_CACHD;

// Update DMA channel 0 with original descriptor and arm channel if it was
// in use before PM was entered.
DMA0CFGH = storedDescHigh;
DMA0CFGL = storedDescLow;
DMAARM = DMAARM0;
// Wait until HS RCOSC is stable
while(!(SLEEP & SLEEP_HFRC_S));

// Set LS XOSC as the clock oscillator for the Sleep Timer (CLKCON.OSC32 = 0)
CLKCON &= ~CLKCON_OSC32;
// halPowerClkMgmtSetMainClkSrc(CRYSTAL);
}
}

and while if i run the simple LED toggle it works fine.
