Package: zram-tools Version: 0.3.5-1~exp1 Severity: important Dear Maintainer,
Since installing latest kernel 6.12 (I use sid), the only algos available are lzo-rle and lzo, as can be verified by root@siddie:~# cat /sys/block/zram0/comp_algorithm [lzo-rle] lzo However, in the default settings /etc/default/zramswap , the compression algorithm is set as ALGO=lz4 , which makes the zramswap.service to fail with the log as follows: Dec 08 02:21:06 siddie.localdomain systemd[1]: Starting zramswap.service - Linux zramswap setup... Dec 08 02:21:06 siddie.localdomain zramswap[4543]: /usr/sbin/zramswap: line 53: echo: write error: Invalid argument Dec 08 02:21:06 siddie.localdomain root[4550]: Error: setting compression algo to lz4 Dec 08 02:21:06 siddie.localdomain zramswap[4550]: <13>Dec 8 02:21:06 root: Error: setting compression algo to lz4 Dec 08 02:21:06 siddie.localdomain systemd[1]: zramswap.service: Main process exited, code=exited, status=1/FAILURE Dec 08 02:21:06 siddie.localdomain systemd[1]: zramswap.service: Failed with result 'exit-code'. Dec 08 02:21:06 siddie.localdomain systemd[1]: Failed to start zramswap.service - Linux zramswap setup. The problem can be temporarily fixed two ways: - Manually change ALGO=lz4 in /etc/default/zramswap to one of the supported algorithms, ALGO=lzo (or ALGO=lzo-rle ) or - Use an earlier kernel (less than 6.12) I am reporting this because the defaults fail with most recent kernel; and I am not sure if it is just for this kernel, or this is how it is supposed to be in the future.
