rdomain related interface configuration via hostname.if(5) broken in current
configuration of IP addresses via hostname.if(5) is currently broken for lo(4) in case it's an auto-created interface in the context of rdomain usage (i.e., putting em0 in rdomain 1 auto-creates lo1). The problem persists at least since Feb, 23rd and can be worked around by simply configuring an IP address for lo1 via ifconfig command in /etc/rc.local Example: # cat /etc/hostname.em0 rdomain 1 dhcp # cat /etc/hostname.lo1 inet 192.168.1.1 255.255.255.0 NONE This kind of config previously worked well in the following way: - rdomain 1 was created - em0 was put into rdomain 1 - lo1 was auto-created and put into rdomain 1 - /etc/hostname.lo1 added an IP address to the lo1 interface (which remained in rdomain 1) Since the breakage, this config fails to create rdomain 1. Adding a (previously redundant) "rdomain 1" statement to /etc/hostname.lo1 also doesn't solve the problem. Please let me know if you need further infos on my specific config.
panic i386 trapsignal kernel lock
Hi,
When executing the libc ieeefp/except regression test, the i386 kernel
panics.

mpi@ has added the KERNEL_ASSERT_LOCKED() two days ago in kern/kern_sig.c
revision 1.216

Fix a TOCTOU race that causes signals to be delivered more than once.
The race is only triggerable if one of the threads of a multi-threaded
program is in the middle of a NOLOCK syscall when a signal is received.
The problem is that `ps_sigact' is shared between threads so its access
should be serialized. In the case of SA_RESETHAND, the handler is reset
when a signal is delivered, so delivering the signal twice would put the
process in an "impossible" state where some threads were stopped and some
were waiting for the others to die.
Serialize signal checking & processing with the KERNEL_LOCK() for now,
and introduce postsig_done() gypped from FreeBSD, to make sure the lock
is held when resetting the handler.
Bug report from espie@, ok visa@
Is there just a kernel lock missing around trapsignal() in npxintr()?
And what about psignal(), in other places it is called with kernel
lock.

[SOLVED] Re: HDMI can't be used as primary monitor
Hi Jirko, Thank you for quick response and the URL. I used the machine on other HDMI device and there xrandr worked fine. So xrandr worked and I was able to use the HDMI. Thanks Mark to pointing me to current version. The upgrade via snapshot was smooth.
