Spurious irq 95: 0xffffffdf, please flush posted write for irq 37 and softirq kernel thread consumes 95% cpu

Dear TI/Forum members

  Hardware: OMAP 3503

  Software : Linux Kernel  (from TI PSP linux-02.01.03.11 ) v2.6.29 

  Ethernet :  LAN 9220  SMSC

  Problem : Occasionally when we try to restart the eth0 interface when changing the IPv4 configuration, we run into two issues

        Issue 1:  The   "Spurious irq 95: 0xffffffdf, please flush posted write for irq 37" is logged by kernel (seen via dmesg command)  , this message is seen a 2 to 5 times , and no more

       Issue 2:   The kernel thread  "softirq"  consuming a very high percentage of CPU,  95% , and any operation on the system becomes very very slow , the only way to recover from this issue is to hard reboot system.

Has anyone of you face these two issues,  any pointers to resolve these issue would be great

 

thanks
