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: [email protected]
Reporter: [email protected]
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 == 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, however 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.
