I created a swap file on the embedded target using dd if=/dev/zero of=/SWAPFILE bs=1k count=8192 mkswap /SWAPFILE But when I try to enable swapping using "swapon /SWAPFILE", linux complains that it can't find a swap signature in the file. I've looked at the file using a hex dump and it seems to be in the right place (10 characters at offset 4096-10). Adding some debug printk's, I can see that sys_swapon() reads in random data (usually NULLs, but not always) into a swap_header struct. I get the same result with v0 and v1 swap file formats. I tried creating the swap file on my PowerMac G3 (running linux-2.2.10) but that yielded the same result. My kernel is the embedded 2.2.13 running on a custom mpc860 board. The system's NFS root is served from a cheapie x86 system running linux-2.2.13. Any thoughts? -Jim ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
