Hi, Manish, Your best bet is to raise a PR with all the detail you can. freebsd-questions@... tends not to be read by all of the kernel developers who might be in a position to help you out. If you can, try and generate a backtrace according to the instructions in= https://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/ker= neldebug-gdb.html If nothing else, this should indicate where in the kernel things went wrong, which will help in directing your report to someone with relevant knowledge.
