No, I wan't using linux_kdump, thanks for the education.
Today I've installed linux_kdump from the package on
jp.current.freebsd.org, and now I get
1207 vmware CALL linux_access(0xbfbff759,0x4)
1207 vmware NAMI "/compat/linux/home/hunter/gwk/.Xauthority"
1207 vmware NAMI "/home/hunter/gwk/.Xauthority"
1207 vmware RET linux_access -1 errno 13 Permission denied
which looks a little more meaningful (no negative errno any more, and
a linux_* syscall is listed).
Still needs debugging, which I'll attempt to do when I get a little
time.
