Hi All, We have ported U-boot and Linux-2.4.22 onto a custom powerpc 8280 board. We were successful in booting Linux from Hard Disk also(Hard Disk is connected to a serial ATA card which sits on PCI. We ported the Serial ATA driver to U-boot from libata source. U-Boot identifes the Hard Disk and we are able to read and write to the hard disk from U-Boot). Once the linux comes up, the Hard Disk is being identifed as a SCSI device. We have created a swap partition in sda3, and our filesystem resides in sda4. We have 256MB ram. The problem what we are facing is, when we try to untar a huge file (EX: linux-2.4.22.tar, size 158MB), the board hangs after some time. We observed the available ram space from other window, when untar was happening, using "free" command. We found that the "used" area is continuosly increasing and the available free ram space is decreasing. At one point of time, when the free ram space exhausts, the board is hanging. On a x86 system, the "used" space of ram keeps varying, but on our PPC board, it's continuosly increasing. We tried enabling the swap (on /dev/sda3), but even then the result is same. What is the reason for this? Are we missing some configuration?
