Hello, I have a Dell 2950 where my 7-CURRENT amd64 FreeBSD does not see all visible memory. It has 4 GB of physical RAM. dmesg on boot includes:
usable memory = 4280811520 (4082 MB) avail memory = 4117716992 (3926 MB) Yet summing memories visible in top yields ~ 2100 MB. Of note is that I have 6.2/amd64 on several other 2950:s with 4GB of RAM which say on boot: real memory = 5100273664 (4864 MB) avail memory = 4122443776 (3931 MB) But has all 4 GB visible in top. Unfortunately I failed to notice this until after the machine has begun being used, so I have limited possibilities for rebooting/mucking with BIOS settings. I was hoping someone could suggest something right off the bat. In addition on the problem machine the following sysctl values are present: hw.physmem: 4280811520 hw.usermem: 3628220416 hw.realmem: 5100273664 hw.cbb.start_memory: 2281701376 hw.pci.host_mem_start: 2147483648 With hw.usermem being slightly higher (but not 2 GB higher) on the 6.2 system without a problem: hw.physmem: 4283285504 hw.usermem: 3998797824 hw.realmem: 5100273664 hw.cbb.start_memory: 2281701376 hw.pci.host_mem_start: 2147483648 I was under the impression that memory visibility issues were a thing of the past on amd64. Any insight?
