Public bug reported:
Hello,
we are working with the Ubuntu 16.04 developer preview. Yesterday we
observed a kernel panic of the installer kernel on one of our machines.
The machine is of type
Supermicro X10DRH LN4/X10DRH-CLN4, BIOS s1.0b 12/01/2015
We are installing the machine via PXEboot with the netboot installer
system using the following kernel/initrd:
dists/xenial/main/installer-amd64/20101020ubuntu446/images/netboot/ubuntu-installer/amd64/initrd.gz
dists/xenial/main/installer-amd64/20101020ubuntu446/images/netboot/ubuntu-installer/amd64/linux
When using this version the kernel crashes (see attached log file). We
have also tried the version 447 instead of 446. This version shows
the same effect.
Some time ago we worked with the installer version 441. This release
worked as expected.
Someone out there knows what has changed? It seems that the kernel has a
problem with the harddisk IO system. In our machine the mpt3sas disk
controller is required to get access to the harddisks.
If I should test some new stuff please let me know. Or if I can help you
in some other way to solve this issue contact me.
Thank you for your help
Dr. Johann Pfefferl
