Kernel Panic on DL140 G3

Hello!

I have a DL140 G3 with Xeon 5110 1.6Ghz 64bit CPU and 2GB ram.
I got a Kernel Panic when I boot a 64bit Gentoo install CD. And also when I boot Suse 64bit install CD.

32bit install CDs works fine.

Is there anyone who managed to boot 64 bit Linux on these machines?

Jonas,

Xeon isn't 64-bit CPU, but 32 bit CPU with EMT64. (see http://en.wikipedia.org/wiki/X86-64 for details )
In short, you can install or 32bit distro, or x86-64 distro.
64-bit distro is for Itanium box.

Rgds,

Hello Vitaly,

Thanks for you reply.
But both Gentoo AMD64 and Suse x86_64 fails to boot. Im not trying to boot IA64.

Re: Kernel Panic on DL140 G3

I suggest you try RHEL (or free CentOS ) or SLES - these distros are certifed for DL140G3.

I will try these tomorrow.
I heard that some early Xeon 5110 didn't support EMT64. Maybe I got one of them?

Re: Kernel Panic on DL140 G3

how can we check in linux if our CPU supports EMT64? to say the true, I don't know....

According to http://www.intel.com/products/processor/xeon/ , Xeon 5100 supports EMT64...

Re: Kernel Panic on DL140 G3

If you have a new enough kernel, (after May 2002), then the /proc/cpuinfo "flags" line will include an "lm" flag for CPUs that implement EM64T. The "lm" stands for "long mode". The bit is common to Intel and AMD CPUID mechanisms. It is documented on page 35 of http://download.intel.com/design/Xeon/applnots/24161831.pdf

Thanks!

Im a little bit disapointed at HP. HP sell this server as EMT64 and ship with a CPU that don't have this capability. :(
Atleast it has virtualisation capabilities.
