My system have 65Mbytes RAM on the board, and it uses 256 Mbytes as swap devices. I tried the same on the PC-386 linux, it comes in about 2-3 seconds for 120G Reiserfs. I use linux2.4.18 on my PC. According to your openion and FAQ on www.namesys.com , there may be two issues; one is RAM shortage for bitmap, another is to use Linux2.4.13 or above for ARM platform. Could it be both? Could you help me what( or how) I need to investigate?
