I've tried this with 5.1-RC1, and nothing happened. Their were simply no more kernel messages after probing the amrd device. The machine appears to hang, and the video disply still turns off.

I've recently seen similar problems on a friend's i810-based Toshiba Equium 3100M - with 4.7, 5.1, and some unknown incarnation of RedHat. I tried upgrading the BIOS and resetting it to "safe" defaults on the off chance that it was some kind of power management bug, to no avail.

For those who find they may need to disable acpi, you can selectively disable different components. Larry, since yours is on battery transition, try "debug.acpi.disable.ec=1" or possibly one of the other options. I recall that you had a thermal problem also. For Paul, who was having irq probing issues, try "hw.acpi.pci.link.%d.%d.%d.irq" to set it explicitly while leaving ACPI enabled. http://www.freebsd.org/cgi/man.cgi?query=acpi&apropos=0&sektion=0&manpath=FreeBSD+5.0-current&format=html I have been working on Campi's and LER's problems. But I only do this in my free time. Your best bet is acpi-jp@ as the Intel people are very good at this.

Expect the 5.2 TODO to trickle in every few weeks for the next few months, and feel free to submit updates to the TODO list to [EMAIL PROTECTED] I should say, of course, that the primary goals for 5.2 are not new software features (although those will happen too), but improved performance, robustness, and usability across all of our platforms, so don't submit too many feature TODO items that will distract people from making that happen :-).

And I hoped a programmer who knows the source could find out and fix
very quickly.
sorry, i missed the offending line number in your previous email.
I think i missed a & in all the first arguments to bcopy in
the src/sbin/ipfw2.c changes :(
this happens at lines 818, 1224, 1461 and 1701. Fortunately
the kernel part seems correct.
In detail, the fix should be the following:
818:
- bcopy(rule->next_rule, &set_disable, sizeof(set_disable));
+ bcopy(&rule->next_rule, &set_disable, sizeof(set_disable));
1224:
- bcopy(d->rule, &rulenum, sizeof(rulenum));
+ bcopy(&d->rule, &rulenum, sizeof(rulenum));
1461:
- bcopy(((struct ip_fw *)data)->next_rule,
+ bcopy(&((struct ip_fw *)data)->next_rule,
1701:
- bcopy(d->rule, &rulenum, sizeof(rulenum));
+ bcopy(&d->rule, &rulenum, sizeof(rulenum));
Look way bettter now :)
I wasn't able to crash the kernel with missaligned access any more, but
the userland tool still does in some situations:

I'm currently using the attached diff to ipfw2.c + your other changes.
It seems to work now.
I hope that I catched all missalignemts that were missing.
Thanks for the work on this.
I'm very happy to see this running on alpha.

I'm currently using the attached diff to ipfw2.c + your other changes.
It seems to work now.
I hope that I catched all missalignemts that were missing.
Thanks for the work on this.
I'm very happy to see this running on alpha.

The first time I thought: sure, there's something open on it... with 3 xterms open where I use zsh as the shell it was easy to hunt for a program which I may have suspended, but I wasn't able to find one. Even "umount -f" wasn't able to umount the slice. As the disk was used to transport some data I wasn't able to look further into this. Now with a new kernel (from May 30) and another data transport on a harddisk I'm not able to reproduce the problem (a May 25 kernel failed to umount the slice).

A gdb stacktrace is much more than "without further details". It happened inside bcopy. I asumed that the stacktrace including the sourceline calling bcopy would be enough.

It's a chick egg problem - if software regulary fails then less users will use such hardware or at least avoid that kind of software. Don't get me wrong: ipfw is good software which I use daily (on i386) and I'm happy about the recent features you did, but there are two sides of the story. -- B.Walter BWCThttp://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"

No. My suggestion would be to not load something into a global page before some of the VM system mappings have been established. Basically, there is some machdep.c code that's out of order. Reordering it is hard, so I haven't done it yet. In other words, the problem is that someone is enabling PG in %CR0 way too early. Read the first sentence again: "...works around an order of operation problem...". I think if you check the archives back to when I first started recommending that both DISABLE_PSE and DISABLE_PG_G be used, rather than just DISABLE_PSE, it comes down to the machdep.c and locore.s reorganization, where I complained that the new order of operation had problems. This happened back before the 5.0 DP1. My suggestion then was "revert the changes"; barring that, someone is going to have to sit down and go through the new code, like I went through the old code, and understand where every byte of memory is coming from, and how and when it gets into the memory map. I personally think this is probably the responsibility of the people who changed the code and broke use of PG in the first place. -- Terry ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
