Hi,
I have a couple of new Dell PowerEdge 2950 with 16GB RAM and I found
the following issue when trying to install FreeBSD.
FreeBSD i386 6.4_RELENG
=======================
8 GB RAM: OK except "acpi_alloc_makeop_handler: can't alloc wake
memory" corrected with PR 120515
16GB RAM: panic: "pmap_mapdev: could'n allocate kernel vistual memory"
when loading miibus
32GB RAM: panic as soon as the kernel loads, cannot read the error
message (several pages)
FreeBSD i386 7.1
================
Plain distribution, I have not yet upgraded to RELENG.
It reports for each CPU, on GENERIC and PAE kernel:
cpu0: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 471b471b0600471b
8 GB RAM: OK
16GB RAM: OK
32GB RAM: panic as soon as the kernel loads
I got the 32GB RAM by combining the memory from both servers.
I'd prefer using legacy kernel (6.4) but I beleive 7.1 is OK too.
One of the server will not be installed for a while and I could run
test on it if I am directed what to doo.
I can repost to a more appropriate list if I am told what list would
be the best.
TIA,
Olivier
