Hi guys, I just found out that there is this awesome zram module for complessing swap in memory... for ones who don't know what zram is please read this article: http://blog.woralelandia.com/2012/02/12/howto-use-zram-on-fedora-16/ I got this error when loading zram module on 64 bit Fedora 17: modprobe zram FATAL: Error inserting zram (/lib/modules/3.4.6-1.fc16.x86_64/extra/staging/zram.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg [20670.805900] zsmalloc: Unknown symbol alloc_vm_area (err 0) [20670.805932] zsmalloc: Unknown symbol free_vm_area (err 0) [20670.805959] zsmalloc: Unknown symbol __supported_pte_mask (err 0) I tried loading on my other laptop that uses 32bit Fedora 17, and it is same issue. I'm not sure if this is an issue with the zram source code or some packaging issue.
