BF537 bfin_reset() in reboot.c hangs after a cmdline reboot

System: BF537, uClinux 2011R1-RC3
             SPI master mode boot (BMODE = 011). Booting from Serial SPI Flash (M25P128) into DRAM.
             Using a JFFS2 root file system.

 

Intermittently, more often than not, when I telnet in to my BF537 system, and execute
the reboot cmd, the reset hangs in bfin_reset() in reboot.c.

 

Prints show that the hang occurs when calling:

 

    bfin_write_SWRST(0x7);

 

Can anyone shed some light on this?
