Hello,
Kernel 6.5.0 or previous one was working fine. At reboot, kernel 6.8.0 was used and it was impossible to get card temperature or do continuous reading (a finite read of few samples was still working)
Issue was root-caused thanks to kernel logs with some issue around PCIe write requests (and is in fact seen by other people, mostly for graphics cards)
Solution is to add intel_iommu=off on kernel cmdline (in /boot/grub/grub.cfg for example) or disable VT-d in the BIOS (generally in Advanced Setup section)
