2.6.20 unaligned accesses

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On a Sun T1000 running 2.6.20 I'm seeing lots of these:

Kernel unaligned access at TPC[63d47c] Kernel unaligned access at TPC[63d47c] 
Kernel unaligned access at TPC[63d47c] aoenet_rcv+0xa4/0x190
aoenet_rcv+0xa4/0x190
aoenet_rcv+0xa4/0x190
Kernel unaligned access at TPC[63d47c] Kernel unaligned access at TPC[63d47c] 
Kernel unaligned access at TPC[63d47c] aoenet_rcv+0xa4/0x190
aoenet_rcv+0xa4/0x190

Google found similar reports and fixes by David Miller (cc'ed), suggesting 
that more agressive structure packing by gcc 4.1.1 was exposing buggy code, 
so perhaps this is a similar case? (I am also using gcc-4.1.1)

Is this just an 'unaligned accesses are slower' issue, or simething more 
serious?

Let me know if I can do anything to further diagnose or test.
