If so, please can you provide version where it works? It is suspend to encrypted swap? There should not be any recent change in dm-crypt related to this path, so I expect it is some bug related to suspend/resume in combination with running crypto - like corruption of some memory caused during suspend... > [lots of snippage] >> [69186.618357] RIP: 0010:[<ffffffff8031f246>] [<ffffffff8031f246>] crypto_xor+0x7/0x48 > [69186.618468] [<ffffffffa027226a>] ? crypto_cbc_encrypt+0xfa/0x15a [cbc] > [69186.618481] [<ffffffffa0285705>] ? aes_encrypt+0x0/0x7 [aes_x86_64] > [69186.618494] [<ffffffffa020667d>] ? async_encrypt+0x35/0x3a [crypto_blkcipher] > [69186.618509] [<ffffffffa0269a6f>] ? crypt_convert+0x1d2/0x253 [dm_crypt] > [69186.618522] [<ffffffffa0269ed6>] ? kcryptd_crypt+0x3e6/0x407 [dm_crypt] > [69186.618533] [<ffffffffa0269af0>] ? kcryptd_crypt+0x0/0x407 [dm_crypt] I assume that crypto run here synchronously (not through asynchronous completion callback). Herbert - is my guess ok? (The asynchronous handling in dm-crypt was the only part changed recently.) (And I think that except crypto hw nobody uses asynchronous mode yet by default.)
