Then you are having some other sort of kernel abort. There should be a kernel message PRIOR to entering ddb and getting the standard "provide trace and ps" messages and the ddb> prompt. Capture that message. In addition, capture the complete output from trace.

ok, I'll do that.
Actually it just happened again with the Planet card, so it should not be the nic problem.

Vermaden at the beginning asked if my cooling is working properly. Now I'm starting to pay attention to anything, and I have to say that when the system boots the fan goes on for a few seconds (I guess it's the bios testing it) and then it never goes on again, but it did in the past, when I tried to recompile the kernel for example (not this kernel, this is a standard install).

hello
here is what first comes out hilighted in blu on the screen:
Code:
Stopped at	0x58b3:uvm_fault(0xd07e9980), 0x50000, 0, 1) -> e kernel: page fault 

trap, code=0
Stopped at	db_read_bytes+0x14:	movb	0(%edx),%al
ddb>
then I typed "trace":
Code:
ddb> trace
db_read_bytes(58b3,1,d6a87d20,2,d6a87ddc) at db_read_bytes+0x14
db_get_value(58b3,1,0,2,0) at db_get_valuee+0x24

Decidedly odd. db_read_bytes is inside ddb -- your uvm_fault shown here occurred after ddb had already been called; which means this is the second panic/fault, and not the primary problem.

Something is definitely out-of-whack. What, though, I cannot tell with any certainly.

If this secondary uvm_fault trap is in any way part of the problem, note that these are problems in virtual memory (paging/swapping/RAM). It isn't necessarily hardware; even so I recommend lots of memtest86, see if it an overnight test shows anything.

I see, thanks a lot
I'll try what you say. Is the memtester in the packages as reliable as memetest86? This machine long ago lost its floppy and cd drives which were in a n external dock, so I cannot do such a test without booting the system (no usb boot support in bios).

"Reliable" is probably the wrong adjective. I have never tried it, but it cannot possibly be as robust and thorough as memtest86. It has fewer tests, and cannot test all sections of RAM as there is a running operating system in the way.

How did you install OpenBSD?

I took out the hd and with an ide adapter used the box where I have windows installed, then put it back in. HP Omnibook has a slot on the side from where you can just pull out you hd without opening the case, very nice.

I thought you previously ran memtest86?

That could very well be the cause of the problems.. defective memory...

sorry, I misspelled, in fact I was running memtester from the packages
I'll try and take out the extra ram module I installed a few years ago, and see if with the original ram it will work.

this time it didn't even boot it went into ddb> right after the "Copyright..."
This is what came out:

Code:
kernel: page fault trap, code=0
Stopped at	uvm_page_init+0x413:	repe stosl	%es:(%edi)
uvm_page_init(d092cf2c,d092cf30,d092cf38,d0357be8,d078aad0) at uvm_page_init+0x143
uvm_init(d06ac675,d06aeb40,d092cfa0,d033dcdb,3) at uvm_init+0x3d
main(0,0,0,0,0) at main+0x4e
ddb>
and trace gives:
Code:
ddb> trace
uvm_page_init(d092cf2c,d092cf30,d092cf38,d0357be8,d078aad0) at uvm_page_init+0x143

If I understand what happened -- I may be wrong -- this happened during initialization of the virtual memory subsystem during boot. If this happened with just the "original RAM" in the computer -- I can think of only two possibilities: either your "original" RAM is bad, or your "original" RAM is insufficient to boot. You need at least 24-32MB of it.

the original ram is 64, so it's enough
Now it booted and works, sometimes it works and sometimes not, I guess it's normal if it's a ram problem?

Intermittent problems are common, yes.

Since you cannot boot memtest+ or memtest86, there is no easy for you to confirm this trouble is due to RAM, but it certainly seems likely.

yes, well this laptop is really quite old and had a quite rough life, maybe it's time for it to rest for good
When I'll have some time I'll try a clean install to make sure it's not a software problem.

Thanks a lot anyway to you all

Why not take out the original RAM module and put the new one in by itself? or vice versa? to determine which is the defective module. (Because that's the leading theory..).

Anyway, hope it works out for you..

It may be that the "original RAM" is embedded in the motherboard and may not be removed, else gosha would have done that already.

jggimi is right


I'm saving money for a NICE laptop, hope to get one next winter, thinking about a Thinkpad x61s (I want a light one).

Perhaps your other PC can be used to confirm the old laptop is the root cause? No traps or panics, using the old laptop's hard drive on a different platform, would mean that your problem isn't due to software.
