VIA x86-64 bootlogs needed

[Andi Kleen]

Hi,

For some APIC code rework I would like to collect some statistics on
VIA APIC setups.

If you have a system with VIA chipset running a recent (2.6.16+) x86-64 kernel 
please boot the system with apic=verbose on the kernel command and send me

- boot output (/var/log/boot.msg or dmesg -s100000000 output after boot)
- dmidecode output
- lspci  -v output

Thanks,

-Andi

MSI Master2-FAR with VIA K8T800, kernel-2.6.17-1.2157_FC5

With any luck, this APIC rework will fix this board's habit of
spontaneously turning off interrupts at the IOAPIC level without the
kernel's knowledge.

Unlikely unfortunately. How does it look like when they get turned off?

I stop getting any interrupts from the device in question (either the
on-board UHCI controllers or the on-board SATA controller) -- i.e. mouse
movement gets jerky because uhci-hcd is operating purely by polling or I
start getting libata timeouts in my logs.

I have an abomination of a systemtap script which calls
unmask_IO_APIC_irq directly which instantly "fixes" it when things go
wrong.

I also have another stap script which records stack traces when
mask_IO_APIC_irq and unmask_IO_APIC_irq called in order to check if the
IRQs are actually getting turned off without the kernel's knowledge, but
when I run that in the background, the problem doesn't ever manifest
itself.

I have the same mobo running latest 2.6.18.  Let me know if you need my
info too.

This APIC rework have the goal of resolve problem with lost tickets ?

What is a lost ticket? 

But unlikely. In fact it only cleans up some code.

Hi, where is my Pentium Dual Core on a 775Dual-880Pro
http://www.asrock.com/product/775Dual-880Pro.htm

Kernel is 2.6.18-rc2 (with some minor patches) from Fedora/RedHat
development. 

I have to boot with notsc, details of the bugs on this computer:
http://bugme.osdl.org/show_bug.cgi?id=6419

Thanks,
