Hello, I tried to install Ubuntu 9.10 Karmic beta release to an AoE disk. Running vblade on Ubuntu 9.04 Jaunty server.
Installation works fine but at 80% it hangs with "Scanning the CD-ROM..." and I find following error in dmesg output: [ 1491.897974] ------------[ cut here ]------------ [ 1491.897976] kernel BUG at /build/buildd/linux-2.6.31/drivers/block/aoe/aoeblk.c:177!

On the server I have running vblade version 16-1ubuntu2, but I also tried a self compiled vblade version 20. The client runs the Ubuntu 9.10 standard kernel which is 2.6.31-11 with aoe module version 47. I'm not sure if it's AoE fault or ext4 but I don't know how to investigate this further. So please let me know if you have any clue how to find the problem :-) best regards, Christoph ------------------------------------------------------------------------------ Come build with us!
