https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235016 david@dcrosstech.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |david@dcrosstech.com --- Comment #1 from david@dcrosstech.com --- I have this problem too (12.2); I did a diff between the 11.2 and 12.0 bran= ches and I noticed that 12.0 introduced MSI interrupts for all drivers in this class, I commented that out via an #if 0 and recompiled and ran, and everything works currently. I loaded the design specs for this and confirmed this does support MSI, so I don't think this is a long term solution. I do have a spare one of these c= ards (I think it is the same chip), and some kernel development experience, but = none with PCIe.. I am willing and able to work on the correct solution, I will = just need some guidance. (I will first experiment with removing the limit on the number of MSI interrupts) --=20 You are receiving this mail because: You are the assignee for the bug.=
