Dear Sirs.
First, please do not reply on this address, your reply will never reach =
me. Please contact me at ohartman@web.de. I can not post into this =
newsgroup via web.de due to SPAM exclusion of several web.de hosts.
As I reported very often in the past I have still massvie problems with =
SMP enabled on a FreeBSD 5.3-RELEASE-p1 __and__ FreeBSD 5.3-STABLE box. =
The crash is always of the same typus as I can 'watch' how the machine =
freezes and for some lucky moments I am able to switch to the console =
before the box dies definitely and watch what error message comes up.
This machine is a ASUS CUR-DLS maiboard, utilizing the RCC ServerWorks =
chipset, version 3 for Pentium 3 CPUs. At this moment I use two Intel =
1GHz CPUs of the same stepping, but prior to this error report I used =
two CPUs with 866 Mhz and of different steppings, but it seems to make =
no difference.
I also tried a lot of kernel options, especially those which are =
supposed to be critical (means: I switched them off) and I used a =
GENERIC kernel for a while, but it makes no difference. The crash occurs =
while using a graphical console, Xorg X11 (version 4.7.0 as compiled =
from the ports), fvwm2 (develepmonet version, but crash occurs also with =
windowmaker so the GUI seems not to be an issue). I also tried to fix =
the problem by using built in fxp-NIC instead of the 64Bit Intel GBit =
LAN adapter (em0), but it is always the same.
I will append a mptable -verbose -dmesg output for your information and =
I will add the error message I receive.
Most time when the crash occurs I did a lot of graphical load (working =
on several TIFF files 200MB in size or with Mozilla/FireFox), but this =
may simply trigger or fasten up the problem.
Sometimes I can not get a 'systat -vmstat 1' output, calling vmstat in =
systat results in 'Alternate system clock has died. Reverting to =
''pigs'' ...'. This happens very often in SMP, but not in UP.
I will add, that the UP system (SMP disabled by kern.smp.disable=3D'1' =
in loader.conf) was up for nearly 13 days under same conditions when a =
SMP box crashes after several minutes, sevral hours.
This is the last console error I received:
Fatal trap 12: page fault while in kernel mode
cpuid =3D 1; apic id =3D 00
fault virtual address =3D 0x1c
fault code =3D supervisor write, page not present
instruction pointer =3D 0x8:0xc062ac76
stack pointer =3D 0x10:0x4e2d7ac

current process =3D 44 (swi5: clock sio)
[thread 100042]
Stopped at vref +0x16: lock cmpxchgl %edx, 0x1c(%edx)
I am not a technical thug nor a kernel programmer. I tried to figure out =
what command got executed at address via recommended mn -n kernel|grep =
c062ac76
and it results in 'T vref'.
What is 'swi5: clock sio'? Is this problem hardware related? Why only in =
SMP? Others seem not to have problems with 5.3 and SMP, maybe this is =
very specific to me due to the RCC based mainboard I use (in the past I =
had a lot of problems with a TYAN 2500 mobo also based on ServerWorks =
chipset in conjunction with FreeBSD 4/5).=20
