ext3 in full journaling mode (Score 2, Interesting)

Im also running a cutdown knoppix OS on an SBC using 1GB CF. The stock distro shipped with 2.4 kernel with no ext3 support and we experienced fs corruption on shutdowns during periods of high disk write activity using ext2. I hand rolled a 2.6.13 kernel with compiled in ext3 support and this has increased realibility when using full jouranal mode (not ordered or writeback). A word of warning, most underlying flash is going DMA enabled; we've been buying Kingston pro elite which was working perfectly in pio mode. Kingston bless them have now changed to samsung DMA enabled flash, and still call the product Pro Elite, its even got the same P/N, but its completly different underlying technology. Our CF slot has pin 34 (DMA pin) NC (not connected). You can set ide=nodma in grub / lilo but we're still seeing CF corruption on DMA enabled CF. Ive changed to Lexar 40X standard - non DMA part and 100% relibility restored. YMMV. But different CF brands seem to behave differently wrt curruption in DMA enabled mode. Ive called Kingston tech support and sandisk both claim all their technology is going this way.
