Hi, I apologise in advance if I've cc'ed too many/the wrong people/lists. Whenever I try to use zram with lz4, on my Power Mac G5 (tested with kernel 4.4.0-16-powerpc64-smp from Ubuntu 16.04 LTS), I get the following on my dmesg: [13150.675820] zram: Added device: zram0 [13150.704133] zram0: detected capacity change from 0 to 5131976704 [13150.715960] zram: Decompression failed! err=-1, page=0 [13150.716008] zram: Decompression failed! err=-1, page=0 [13150.716027] zram: Decompression failed! err=-1, page=0 [13150.716032] Buffer I/O error on dev zram0, logical block 0, async page read I believe Eunbong Song wrote a patch [1] to fix this (or a very identical) bug on MIPS, but it never got merged (maybe incorrect/incomplete?). Is there any hope of seeing this bug fixed?
