Wei, Get off the Ubuntu 2.6.24 kernels. I had nothing but problems with them, especially .24-26. Very buggy. I have been using 2.6.31.6 from Stacklet and things have been rock solid ever since. There are a lot of of other kernels available as well if your machine is 64 bit. Just search the list or check the wiki. Good luck, Dana On Apr 14, 2010, at 11:04 PM, Wei LIU wrote: > Hi, all > > I'm testing Mini-OS's fs-front driver and Xen-3.3.0's fs-backend. > Kernel version is 2.6.24-26-xen, a shipped version of Ubuntu 8.04. > > I uncommented line 1173 in extras/mini-os/fs-front.c, so Mini-OS > should create "fs-tester" thread to do some read/write stuff. > Unfortunately, I got kernel panic.
