I have one of these in my Digital 3305/AS800, it boots without a problem from SRM v5.1-? but it still appears to be having the problem where the root device is not correctly set on installation. When I specifiy the info the system asks for a boot it works ok, but is this issue a bug?

I have seen it mentioned previously on this list. I know that I can work around it by compiling a kernel with "root device on ld0a" to solve this problem though.

Additionally, after having run the system for several days, compiling kernels etc, with the load average at 2-3 for an extensive period, the system started to have problems talking to the raid controller. The following messages were logged on the console:

mlx_ccb_submit: rejected: queueing
[...repeats...]
mlx0: periodic enquiry failed - software timeout (0xdead) 

This controller has firmware revision 2.49, has anyone seen this error before or have any fix etc.

Sound good then, I was getting confused between different card features. At the moment, just booting would be nice!
