Dear Kernel People,

I'm sending to you this message to find out if something is wrong or I should continue
using my system as nothing was happening...

I'm running debian with a 2.4.19 kernel. My motherboard is an intel D865PERL with a P4
2.26, two SATA WD800 disks and a Realtek 8139C nic.

I look forward to hearing from you,

Sincerely,

Agustín

kernel BUG at include/asm-i386/mach-summit/mach_apic.h

Hello,
I have a HP DL760 with 8 Xeon procs in it. Is is running Redhat AS 3 with a customer 2.6 kernel. I have
hyper-threading disabled in the bios. When the machine boots I see the followiing error messages about
CPU 4 and don't really understand the error message. Here is an excerpt from demsg. Also the in the error the
CPU lists CPU #4 but then also lists a different CPU # as not responding right before the  ------[cut here]---
line. If someone could help shed some light on this I would greatly appreciate it.

Thanks

C.

ACPI problem

On our servers only 1 out of 4 cpus is initialized.

We are using IBM x445 4ry with 4 XEON cpus

The kernel is somewhat outdated. At the moment we are bound to this version.
A boot with Knoppix and kernel 2.4.23 did not succeed either.

Do I need to do what is described here:
http://developer.intel.com/technology/iapc/acpi/bios_override.htm
?

Re: lost memory on a 4GB amd64

I just discovered the linux-smp list and decided to summarize the topic 
and take the opportunity to cross-post to there.

an archive of the discussion can be found e.g. here:
http://marc.theaimsgroup.com/?t=109525952600004&r=1&w=4

The machine at hand is the Tyan Tiger K8W with two Opterons 246
(http://www.tyan.com/products/html/tigerk8w.html) and 4GB of memory

we are using vanilla 2.6.8.1 kernel.

 * if the memory is set up in the ordinary way in the BIOS, then
   approximately 512MB are lost (PCI/AGM adressing and stuff), but
   everything is stable
 * if the memory is set up in the BIOS to be in two chunks (e.g. 3GB at 
   the address range 0-3GB and 1GB at 4-5GB address range), then
    - memtest86 tells everything is fine.
    - if we run a non-SMP kernel, everything is stable
    - if we run an SMP kernel, it crashes as soon as approx. 1GB of memory
      is allocated and set to 0 (see the test case C-program in my
      previous mail)

Is there anything we can do? Any logs I can provide? Something to try out?

Thanks,
        Sergei

automatic restarting-reg

Sir,
    We are running Oracle9I Database on linux2.1As. Some times the Server is rebooting automatically during
night time even though there is no load on the system.

    After Opening the dmesg file, i found an error "MP table in the EBDA can be UNSAFE". kindly give  some
information in this regard and solution for the problem.

               Thanking you sir,

                               MRV Sastry

Re: automatic restarting-reg

This message merely hints that it is possible that the EBDA or XBDA 
(Extended Bios Data Area) can be written to which just so happens to be 
where the MP table is located during boot. Once your system is booted then 
the EBDA is no longer available and the MP table has been read by the OS.

So if you boot fine then all is good!!!
