[Bug 1227345] New: Kernel 6.9 (MicroOS): a single cpu core is available.

https://bugzilla.suse.com/show_bug.cgi?id=1227345 Bug ID: 1227345 Summary: Kernel 6.9 (MicroOS): a single cpu core is available. Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs(a)opensuse.org Reporter: maxime.thirion(a)r-virtuel.net QA Contact: qa-bugs(a)suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 875851 --> https://bugzilla.suse.com/attachment.cgi?id=875851&action=edit htop showing only one core Hello everyone ! Overview: I'm experiencing a really strange problem on two servers, in production, hosted by the Hetzner company. Since upgrading to kernel 6.9, only one cpu core is available, giving catastrophic performance. The strange thing is that the two machines are not identical: The first server has an Intel(R) Xeon(R) CPU E3-1275 v5 with 2x 512Gb NVME SSD and 64Gb ram. The second server has an Intel(R) Core(TM) i7-3770 CPU with 4x 6TB HDD and 32Gb ram. I contacted the hosting company first, who told me they didn't know about the problem. With their suggestion, I restarted one of the machines on their rescue system, which has a 6.9.7 kernel, so it's also very recent, and the problem doesn't exist: all the cpu cores are activated. Steps to Reproduce : Update to kernel 6.9 Actual Results: Only one CPU core is available, and performance is very poor. lscpu gives only one core per socket and only one tread per core. kutta:~ # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 39 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list: 0 Vendor ID: GenuineIntel BIOS Vendor ID: Intel(R) Corporation Model name: Intel(R) Xeon(R) CPU E3-1275 v5 @ 3.60GHz BIOS Model name: Intel(R) Xeon(R) CPU E3-1275 v5 @ 3.60GHz To Be Filled By O.E.M.

Additional Information: Any other useful information. I couldn't find the system in the list but it's OpenSUSE MicroOS, so the servers have a read-only file system and they're in production (which limits my testing and reinstallation possibilities). I did a rollback on the server with the Xeon that was still in 6.4 and the problem no longer appears. I no longer have a snapshop with an old kernel on the i7, as I didn't see the problem immediately. I can do some "tests" on this server if necessary. The servers were up to date (before the Xeon rollback). -- You are receiving this mail because: You are the assignee for the bug.
