Exclamation Instability w/ 2.6.6

I'm using the 2.6.6 kernel, and 5336 installer. I've been using it on 2.6.5, and now I'm getting massive instabilities. Within 5 minutes (time varies, but always within about 5 min), I get a full system lockup (no alt+ctrl+F1 to terminal, nothing).

I'm using:
A7N8X deluxe
5336 installer
GeForce 4200 Ti
Athlon 2600+
4K stack is NOT enabled in kernel

Is this a driver issue? I was assuming that is the case since my exact same config setup has worked with 2.6.0-2.6.5... but I'm certainly not saying that's what it is for sure. Let me know if more info is needed, or what config options I should change.

Default Re: Instability w/ 2.6.6

I just finished downloading the latest 2.6.6 kernel and compiled with
the 4K_STACK option disabled and then installed the NVIDIA-5336 driver.

My system seems to work ( so far ) with no obvious change from
2.6.5. I am running Fedora Core 2 Test 3 with all updates installed up to
5/1/2004. The computer is a pentium III with a 16 megabyte NVidia TNT2 card.

My previous builld was 2.6.6-rc3. Perhaps there is something in your config file that makes the system unhappy.

Possibly, but like I said, this kernel config has worked fine for me in the past (many times, on all 2.6.x kernels). AFAIK, the 4K stack option is the only one I should be particularly worried about, right?

Its good to know that the driver works on some systems at least... maybe with some tweaking it will work with mine.

from the change log
[ACPI] workaround for nForce2 BIOS bug: XT-PIC timer in IOAPIC mode "acpi_skip_timer_override" boot parameter

this should help the stablility but you have to place "acpi_skip_timer_override" as boot parameter

like:
image=/boot/vmlinuz-2.6.6
label=266
root=/dev/hdc1
read-only
optional
append="acpi_skip_timer_override"
vga=normal
initrd=/boot/initrd-2.6.6.img

There is also

[PATCH] fixup for C1 Halt Disconnect problem on nForce2 chipsets
Based on information provided by "Allen Martin" <AMartin@nvidia.com>:

A hang is caused when the CPU generates a very fast CONNECT/HALT cycle
sequence. Workaround is to set the SYSTEM_IDLE_TIMEOUT to 80 ns.
This allows the state-machine and timer to return to a proper state within
80 ns of the CONNECT and probe appearing together. Since the CPU will not
issue another HALT within 80 ns of the initial HALT, the failure condition
is avoided.

You might also want to turn off CONFIG_REGPARM (found in the Processor type and features section). This could also cause instability when used with the Nvidia kernel module.

Default Re: Instability w/ 2.6.6

I get lib errors on ldconfig on boot with 2.6.6 and nvidia drivers. It says the files aren't elf files and the magic number at start is wrong. Also X says the module number format is invalid it uses 6. So I guess I will need to wait for new NVIDIA drivers.

So what do i need to do with this? This is just included in the kernel, right? There's nothing I need to enable here?

I am not 100% sure but to inable the C1halt patch for 2.6.5 (it was included in 2.6.6) you add as a boot parameter idle=C1Halt

if you still get hangups after trying the acpi_skip_timer_override add idle=C1halt (this may do nothing.. you might find the answer hunting through the linux kernel mailing list @ www.lkml.org)

your /etc/lilo.conf will look something like this:


boot=/dev/hdc
install=menu
vga=normal
default="266"
prompt
timeout=50
message=/boot/message
menu-scheme=wb:bw:wb:bw


image=/boot/vmlinuz-2.6.6
label=266
root=/dev/hdc1
read-only
optional
append="acpi_skip_timer_override idle=C1halt"
vga=normal
initrd=/boot/initrd-2.6.6.img

Default Re: Instability w/ 2.6.6

FWIW, same type crash issue with 2.6.6. Used my 2.6.6-rc2 config with no 4kstack, no regparm. 2.6.6-rc2 has run for weeks at a time with no issues.

Have tried the acpi_skip_timer_override suggestion - still crashes.
Rebuilt the kernel with ACPI removed - still crashes. (also acpi=off & noacpi)
It sometimes will not even make it through the disk check on boot. Sometimes to X (w/5336) and then crash/hang

Abit NF7-S v1.1
nVidia Corporation NV15 [GeForce2 GTS/Pro]
2 x Maxtor disks (old ones as some new ones with 8Mb buffer have issues)

No joy for now - back to 2.6.6-rc2. Will look further later.

Have you tried the PNY 5341 version of the driver?

His lockups most likely have nothing to do with the graphics card or driver, but a Nforce2 bios/hardware/kernel bug that is causing the lockup. (it will hang/crash with the nv and no nvidia driver installed.)

A lot people have had lock up problems with the 2.6 kernels and the kernel developers are looking for a work around to fix the issue.
