Kernel BUG on probe

[mar-ven]

I am experiencing a kernel BUG at Coyote/driver/fpga_dev.c:108 (accl_integration branch) I am currently using an Alveo U280. Linux Kernel: 6.5

My steps:

• I made sure that coyote driver was not loaded
• I used Vivado Hardware Manager 2022.2 to load the bitstream
• I ran sw/util/hot_reset
• lspci | grep Xilinx shows that the board is correctly identified
• I launch sudo insmod coyote_drv.ko

This last command hangs, because of the kernel bug.

I also experienced this error previously, with the same setup apart from the Linux kernel, which was 5.15

Another important detail sudo dmesg also gives the following print: detected -268378664 virtual FPGA regions, -268379542 FPGA channels

Some time before this error happened, I experienced another error: AMD-Vi IO_PAGE_FAULT, while I was launching the test.cpp file with options -f -r. This error happened before any test functions were actually run
