mem=32M single

The laptop I’m using for work acted up the other day, and after memtest revealed broken RAM starting after the initial 32MB, I booted it with “mem=32M single” to back up my home before taking it apart. However, the OOM killer would come out and kill everything about halfway into the copying, even if (according to free) about 10MB of memory was used for cache and I had 2GB of swap.

Setting swappiness to 100 delayed the problem quite a bit, but the operation still couldn’t finish. I’m left wondering if stock Linux no longer supports low-memory configurations or if it’s just my distro.
