Thanks for looking into this! Unfortunately, the problem still persists on SPARC even with v6.18-rc6: [ 76.209476] Kernel unaligned access at TPC[8dabfc] aa_dfa_unpack+0x3c/0x6e0 [ 76.301115] Kernel unaligned access at TPC[8dac0c] aa_dfa_unpack+0x4c/0x6e0 [ 76.392697] Kernel unaligned access at TPC[8dacf0] aa_dfa_unpack+0x130/0x6e0 [ 76.485440] Kernel unaligned access at TPC[8dacf0] aa_dfa_unpack+0x130/0x6e0 [ 76.578179] Kernel unaligned access at TPC[8dacf0] aa_dfa_unpack+0x130/0x6e0 I have documented the problem here [1]. So, I suspect that your fix is incomplete. Adrian > [1] https://github.com/sparclinux/issues/issues/30 -- .''`.
