A few months ago I switched from 2.6.16.16 to 2.6.24 on an AU1550 (MIPSLE) system. I started rolling this out to more systems, getting ready for a new software release and discovered that on fresh powerup, the 2.6.24 kernel sometimes (1 in 10-25 power cycles) fails to start. The bootloader (uboot) decompresses the kernel from a jffs2 filesystem and then jumps to it, but I don't get any serial messages from the kernel. If I switch back to the 2.6.16.16 kernel, everything is happy. The annoying thing is that I have been unable to catch the problem with the JTAG debugger connected, so I'm not sure where it is hanging. I've been looking at diffs in the arch/mips tree and nothing has jumped out at me. I don't think this is a hardware problem, this hardware platform has been fairly stable and it works just fine with the older kernel. I was wondering if anyone has any suggestions where I might look? Also, is anyone using 2.6.24 with a Au1550? Thanks, Clem
