Hi,
Im installing 5.3 amd64 on Dell Poweredge servers 2800 and 2850. All
machines have 4 to 8gb of ram and Perc 4e/di hardware Raid controller.
The install does not boot completely because of the amr driver for the
Perc 4e/di not recognising 4gb+. To solve this I specify hw.physmem=4G
at boot time. The system then recognises 3.3gb of the ram.
To solve the issue of the amr driver i took the driver source from
6.0-CURRENT kernel source, replacing the driver in the 5.3 kernel
source with it and compiling a new kernel. This worked and now all
system ram is recognised.
My question is,as these servers will be production servers under a
heavy load a lot of the time,will this new driver be stable enough to
use or is it a risk.
Thanks.
