https://bugzilla.kernel.org/show_bug.cgi?id=115351 --- Comment #2 from Jonathan <spamme@xxxxxxxxxxxxxx> --- clearly if 16 is enough for 2^64 then just get rid of the error message all together, and call it done. I don't know why sd_try_rc16_first() returns zero. I don't even know how to find out. This is all the dmesg reveals: [ 2.520235] AAC0: kernel 7.5-0[32084] Jun 15 2015 [ 2.520240] AAC0: monitor 7.5-0[32084] [ 2.520241] AAC0: bios 7.5-0[32084] [ 2.520243] AAC0: serial ######## [ 2.520244] AAC0: Non-DASD support enabled.
