On sparc, we see unaligned access messages on each modprobe[-r]:
Kernel unaligned access at TPC[6ad9b4] pkcs7_verify [..]
Kernel unaligned access at TPC[6a5484] crypto_shash_finup [..]
Kernel unaligned access at TPC[6a5390] crypto_shash_update [..]

Hi,
I'm getting a lot of unaligned access messages each time I
do "modprobe [-r] " on sparc:
Kernel unaligned access at TPC[6ad9b4] pkcs7_verify+0x1ec/0x5e0
Kernel unaligned access at TPC[6a5484] crypto_shash_finup+0xc/0x5c
Kernel unaligned access at TPC[6a5390] crypto_shash_update+0xc/0x54
