RE: Linux-2.4.0-test10

[CRADOCK, Christopher]

I have a similar hardware list and I don't observe any of these problems on
2.4.0-test10x. Is it possibly a hardware conflict somewhere?

What I do see occasionally is if X was ever heavy on the memory usage (say
I've run GIMP for a couple of hours) then the text console's font set gets
trashed until the next reboot. Console driver failing to reset something?

Hi Chris

Never had the trashed fonts before.

How about a better comparison of systems?
All I mentioned were r128, ne2k, PIIX4 and SMP,  barely enough to claim similar
hardware thus these aren't real problems cause you don't see them.
I can send you gory details if your interested.

My reason for claiming these are problems, maybe not show stoppers, are:

This system is rock solid on 2.2.X.

problem 1, shouldn't fail on 2.4 if it works just fine on 2.2.  Probably a locking
issue but I'm not sure.  Any idea where to put some BKL's to see if the problem
will go away?

problem 2, happens randomly, so is it a hardware problem or a software issue?  being
that the system works fine SMP and UP then my guess is a software interaction when
UP-APIC is enabled, a race condition??

problem 3, new feature in 2.4, one would expect, hey, I've got this hdwr in my system,
let me enable this option...  wait a minute the system doesn't boot...

problem 4, ISAPNP in the kernel is new for 2.4, i was pointing out that it can be
improved to make it better able to select IRQ's that work so that the user can just
upgrade to 2.4 without having to tweak the BIOS and/or the code.  I sent a patch to
Linus but he rejected it, yes I realize it was a weak attempt but it fixed my ISAPNP
problems, and no one has proposed a better solution.  Shouldn't the
first release of 2.4.0 show that it's new capabilities are ready for prime time?


Thanks,
Martin

Well, here never did until today :)   With test9, I had left the box idle
downloading stuff over ppp for like 6h under X.  While wget was running,
switched to a vc and with each dot wget printed, the font map got screwed
up more and more.

Not a particular useful report, but I thought I'd mention it in case it
rings a bell somewhere .. UP instead of your SMP, VIA instead of PIIX.

Just happened with test10, same circumstances .. font map got corrupted, and
noise on the screen.  Switching back and forth from X to a vc fixed it, tho. 

Sort of amusing that it (apparently) only happens with ppp + wget ..

You have a voodoo3 or voodoo5 with X4, and the DRI X4 module loaded.

Or am I wrong?

No! The X server resets the VGA mode including resetting the fonts. See
xc/programs/Xserver/hw/xfree86/vgahw to see how XF4.0 switchs between X
and vgacon. It see under heavy pressure X fails to reset the video
hardware on it own :-(

I have this problem also.  I am running vesafb and X4.01 w/ a voodoo3500.
Switching to a vc sometimes gives you black text (hiliting w/ mouse fixes it) and
alternating green and red pixels across the top of the screen.

Comment out the 'Load "dri"' line from /etc/X11/XF86Config-4, I'm
working on debugging the problems.

another buffer.c:827 BUG, RAID1 reconstruction.

[M.H.VanLeeuwen]

Hi,

I got this BUG report after test12-pre7 soft locked on my NFS server,
all nfsd's in D state and I had to reboot and system was rebuilding the
ide RAID1 arrays.

NFS client test12-pre7 was rebooted as well, root logged in, and ran ldconfig

NFS server BUG'd out

Hand copied OOPS hope too much isn't wrong.

Cache problems on test12-pre?

[M.H.VanLeeuwen]

Hi,

I've notices weird compile time failures etc on test12-pre7, especially
running more than 2 simultaneous processes...

but most noticeable is the time it takes to run ldconfig, after the
first time test11 takes less than 1 second, test12-pre7 takes ~40
seconds.

both were run immediately after reboot on a completely idle system
this system is almost exclusively NFS mounted file systems.

Is this a known problem?
