Netrunner 20 (debian 10) only sees one CPU core on 4-core system
by opnickc from LinuxQuestions.org on (#56SQG)
Heya,
I'm trying to get Netrunner set up on an old server (craigslist find). I was able to get it installed and running, but the OS only sees one CPU core.
The system has two 771 sockets with a Xeon 5140 in each, so a total of 4 cores (I have a pair of E5472's on the way so I can up that to 8 cores). Both CPUs show up in the BIOS so no issues there. As I said before though, only one core is detected by the OS.
Some googling suggested that maybe ACPI wasn't enabled, so I added 'acpi=on' to my grub config. Is there something else I need to do? I'm at a little bit of a loss since I'd expect SMT to be enabled by default on any modern kernel, and it seems like most posts describing similar issues are from the early 2000s.
I'm running kernel 4.19.0-8-amd64. Any help is appreciated!
