panic in drm
Hello,
At my work I see a panic if I do this.
Leaf my computer on screensaver (don't no if that is necessary) and come
back the next morning. My monitor is than black, but the light is green,
so DPMS didn't kick in.
Keys or mouse don't wake up the system. CTRL-ALT-F1 switches to the
console and immediately triggers this panic.
I'm running latest x.org with xf86-video-i810-1.7.4_1. The newer
xf86-video-intel also crashes my system sometimes when I'm working on it,
so a downgraded.
Any ideas, suggestions or fixes available?
Cheers,
Ronald.

This sounds very familiar to me. I think I was seeing the same panic in
2006...
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2006-12/msg00344.html
Can you add this to src/sys/dev/drm/i915_irq.c
if (!dev-irqr) {
return DRM_ERR(EINVAL);
}
just above the DRM_WAIT_ON in i915_driver_vblank_wait() (around line
140), and see if that prevents the panic? Note that I believe this to
be a workaround, and not really the correct fix.

Those changes were positive and increased compatibility with systems greatly, but there were a couple reports of users whose systems preferred the old method used. Those changes are documented here; and yes, I realise you don't get a screen full of continual register dumps, but different people saw different behaviour: http://wiki.freebsd.org/JeremyChadwick/Commonly_reported_issues Also see these mailing list threads: http://lists.freebsd.org/pipermail/freebsd-current/2007-October/078755.html http://lists.freebsd.org/pipermail/freebsd-stable/2007-November/038214.html Secondly, you said you migrated from 6_rel to 7_rel. Do you mean 7.0-RELEASE, or are you referring to the RELENG_7 tag? What tag are you following when doing csup/cvsup?

jdk16 web plugin on FreeBSD 7 AMD64 Issues
I recently installed jdk16 from ports on my FreeBSD 7-Stable AMD64 home server. When I try to access websites that use the Java web plugin, the applets don't load. Checking on about:plugins in Firefox shows the Java plugin listed and enabled. Does jdk16 web plugin work on FreeBSD 7 AMD64?

Try:

It will print something like the following:

If it matches, remove ~/.java directory and try again.

Kelly, the /boot/loader.conf file does not come into play at that stage. Early in the loader code, loader needs to figure out, which disk (BIOS device) has been booted from. Until loader knows which device was booted up, it's unable to access any files (even loader.conf) on your boot device. As I've never seen such a problem while upgrading any system, I suspect your problem must be settings specific. Can you show me your kernel config or are you using a plain vanilla GENERIC? Which arch are we talking about? As I'm currently investigating another boot problem (but earlier in the boot chain), I'll check boot logic in the source code and may check for your issue, too, at that time, so it's just one effort. But please stay patient for some days, as I'm currently too busy.

Performance of madvise / msync
Hi,
I'm using py-rrdtool 0.2.1 with rrdtool 1.3.0 under 7.0-STABLE, and
there's a couple of things about this new version of rrdtool that
hurt performance under FreeBSD, but apparently help on whatever they
tested on.
For every update, the database file is opened, mapped into memory,
madvise() is called, contents are modified, msync() is called, and
the file is unmapped and closed:

As you can see, it's quite a bit faster.
I know that msync is necessary under Linux but obsolete under FreeBSD, but
it's still funny that it takes a tenth of a second to return even with
MS_ASYNC specified.
Also, why is it that the madvise() calls take so much longer when the
program does a couple of its own madvise() calls? Was madvise() never
intended to be run so frequently and is therefore a little slower than
it could be?
Here's the diff between the code for the first kdump above and the
second one.

Try removing just the msync() but keep the madvise() calls and see if the madvise() calls continue to take horrendous amounts of time. Then try the vise-versa. Ok, first off, I'm noticing that of the 4 other files that this is doing the same operations on, sized 569, 940, 116 and 116mB, all of the msync() and madvise() calls are nice and fast. It's only with the 1161524760 byte file that msync is much, much slower. It's not linear -- it hits a wall somewhere between 940 and 1161 million bytes. With madvise() and without msync(), there are high numbers of faults, which matches the number of disk io operations. It goes through cycles, every once in a while stalling while about 60MB of data is dumped to disk at 20MB/s or so (buffers flushing?) At the beginning of each cycle it's fast, with 140 faults/s or so, and slows as the number of faults climbs to 180/s or so before stalling and flusing again. It never gets _really_ slow though. 36286 python 0.16 NAMI rg2.rrd 36286 python 0.25 RET open 7 36286 python 0.09 CALL fstat(0x7,0xbfbfe428) 36286 python 0.14 RET fstat 0 36286 python 0.10 CALL mmap(0,0x453b7618,PROT_READ|PROT_WRITE,MAP_SHARED,0x7,0,0) 36286 python 0.20 RET mmap 679235584/0x287c5000 36286 python 0.10 CALL madvise(0x287c5000,0x453b7618,_MADV_RANDOM) 36286 python 0.10 RET madvise 0 36286 python 0.09 CALL madvise(0x287c5000,0x70,_MADV_WILLNEED) 36286 python 0.67 RET madvise 0 36286 python 0.16 CALL madvise(0x287c5000,0x1c20,_MADV_WILLNEED) 36286 python 0.15 RET madvise 0 36286 python 0.19 CALL madvise(0x287c6000,0x1950,_MADV_WILLNEED) 36286 python 0.13 RET madvise 0 36286 python 0.10 CALL madvise(0x287c8000,0x8,_MADV_WILLNEED) 36286 python 0.10 RET madvise 0 36286 python 0.12 CALL gettimeofday(0xbfbfe554,0) 36286 python 0.10 RET gettimeofday 0 36286 python 0.14 CALL fcntl(0x7,invalid=12,0xbfbfe478) 36286 python 0.21 RET fcntl 0 36286 python 0.040061 CALL munmap(0x287c5000,0x453b7618) 36286 python 0.000324 RET munmap 0 36286 python 0.16 CALL close(0x7) 36286 python 0.44 RET close 0 36286 python 0.000113 CALL __sysctl(0xbfbfe388,0x2,0xbfbfe394,0xbfbfe398,0,0) 36286 python 0.18 RET __sysctl 0 With msync() and without madvise(), things are very slow, and there are no faults, just writes. 61609 python 0.16 NAMI rg2.rrd 61609 python 0.24 RET open 7 61609 python 0.10 CALL fstat(0x7,0xbfbfe428) 61609 python 0.13 RET fstat 0 61609 python 0.10 CALL mmap(0,0x453b7618,PROT_READ|PROT_WRITE,MAP_SHARED,0x7,0,0) 61609 python 0.21 RET mmap 679235584/0x287c5000 61609 python 0.066603 CALL madvise(0x287c5000,0x1c20,_MADV_WILLNEED) 61609 python 0.57 RET madvise 0 61609 python 0.09 CALL madvise(0x287c6000,0x1950,_MADV_WILLNEED) 61609 python 0.10 RET madvise 0 61609 python 0.09 CALL madvise(0x287c8000,0x8,_MADV_WILLNEED) 61609 python 0.09 RET madvise 0 61609 python 0.10 CALL gettimeofday(0xbfbfe554,0) 61609 python 0.18 RET gettimeofday 0 61609 python 0.14 CALL fcntl(0x7,invalid=12,0xbfbfe478) 61609 python 0.26 RET fcntl 0 61609 python 0.004044 CALL msync(0x287c5000,0x453b7618,MS_ASYNC) 61609 python

As I'm currently investigating another boot problem (but earlier in the boot chain), I'll check boot logic in the source code and may check for your issue, too, at that time, so it's just one effort. But please stay patient for some days, as I'm currently too busy. We just got hit by this. The loader never loads and nothing boots. But a system admin discovered that the problem disappeared if the /boot.conf file was deleted. It just contained '-P'. Once this file was removed, the system just booted up as expected. When he changed it to -D or -h, the boot still locked up. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.

Sorry. -P set the console to the serial port assuming no AT/PS2 keyboard is connected to the machine. -D and -h are described in more detail in the Handbook. man boot describes that pretty well, to0. Even with -P, -D, -h, or -Dh, the system *should* still actually boot up, you just won't see anything on the VGA console until the system is fully up and getty/login is run against ttyv0 (VGA console login). The system in question are servers and have no VGA console. They just hung without any sign of the loader, but when he used the old loader, the system booted normally. I thought that /boot.config was read by boot2, so it should be over an done with before loader is even started. All I can think is that the result of having set any of these flags, all of which are related, causes loader(8) to go off the deep end. I think I'll suggest that he try just -s in /boot.config If Kelly has no /boot.config, then I'd say the issue you're reporting is a different bug/problem, but should still be investigated. It may be different or it may be a different manifestation of the same one. Rather hard to tell at this point. I am very busy with preparation for a major upgrade to our Chicago hubs and may not get much chance to play with these now, but I'll ask the admin to give it a shot, along with an empty /boot.config. -- R.
