Hi All,

Recently I hit an OOPS on FPU save/restore in Linux version 2.6.38.8 using aesni_intel_asm.S and aesni_intel_glue.c for native IPSec(netkey) on 32bit System. The same OOPS were found in versions 2.6.39.4, 3.0.x and 3.1.x.But I did not hit this problem in 64 bit system for all these versions.

My platform information: 
"Linux dnsubuntu 2.6.38.8 #7 SMP Sat Nov 12 03:11:12 CST 2011 i686 i686 i386 GNU/Linux"

Please try the latest git tree (rc4).  It should be fixed.

Cheers,

Thanks for your advice.  I have done the same test on version 3.3.0-rc3 and 3.3.0-rc4.  For version 3.3.0-rc3, the Oops problem can be easily repeated in 1 to 5 mins.  For version 3.3.0-rc4, I have tested around 24 hours, no Ooops is found anymore. The problem I hit is proved to be solved in these patches.
