https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227558 Bug ID: 227558 Summary: bhyve assertion failed when writing ACPI tables Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: domagoj.stolfa@gmail.com When bhyve is run using: bhyveload -d test.img -m <anything> test bhyve -A -H -P -s 0:0,hostbridge -s 1:0,lpc -s 2:0,virtio-blk,./test.img -l com1,stdio -c <any> -m <anything> -t test the "bhyve" process aborts with an assertion: Assertion failed: (error =3D=3D 0), function main, file /home/dstolfa/freebsd-head/usr.sbin/bhyve/bhyverun.c, line 1096. I have traced the error to the vfprintf in dsdt_line() inside acpi.c, howev= er I have not been able to use gdb from ports or lldb to debug this effectively = due to various freezes that I've experienced (not gaining control back in the debugger or failing to execute the child in lldb's case). Adding a number of printfs, namely printf("%s\n", bf->f_name); when creating the temporary files removes the bug, but so does adding printfs when the VM shuts down which leads me to believe that this is in fact a code segment corruption rather than a race. --=20 You are receiving this mail because: You are the assignee for the bug.=
