Summary: Blackfin hardware trace sometimes falls out of order

Details:

 

in bug [#6111], we can see the hardware trace gets out of sync and starts decoding the source as the target and the target as the source

 

Hardware Trace:

   0 Target : <0xffa00e04> { _evt_ivhw + 0xb8 }

     Source : <0xffa00de6> { _evt_ivhw + 0x9a } 0xe10a2108

   1 Target : <0xffa00dd8> { _evt_ivhw + 0x8c }

     Source : <0xffa00dc8> { _evt_ivhw + 0x7c } 0x6000

   2 Target : <0xffa00dc4> { _evt_ivhw + 0x78 }

     Source : <0xffa00d4c> { _evt_ivhw + 0x0 } SSYNC

   3 Target : <0x0007b98e> { _debugfs_u16_get + 0xe }

     Source : <0x0007b980> { _debugfs_u16_get + 0x0 } 0x3210
