So, I happen to have a C3600 machine, I have recently updated the ram to 8GB, and compiled the kernel into 64bit mode

Code:

MemTotal:        3856448 kB


If I don't enable Discontiguous Memory in the kernel setup, the kernel doesn't see more than 3.8Gbyte of ram
but if do so, the kernel is unstable, and I get kernel panics

I am on 2.6.29-tasmanian-devil-hp-c3600-64bit.

Any tips?

Is 2.6.29 the Linux kernel version you used? If so, why are you using such an ancient kernel? If not, what kernel version are you using? Does it work with current kernels?

yes, I am on 2.6.29
It's the kernel it was installed when I bought the machine, 8 years ago.
I have just upgraded the ram, and enabled the 64 bit mode

but, it's not stable at all.

so the question is for you: does it work with current kernels?

v3 ?
v4 ?

Current kernels work very well on typical commodity consumer and business grade hardware. I am pretty sure I have never even seen a machine based on that architecture. I have no information whether a recent kernel would work well on your hardware, but I strongly suggest using a current kernel. If it works, you will get numerous other fixes. If it does not, then at least you will be on a kernel that someone might be willing to help you debug.

"Typical commodity consumer/business grade hardware" means the type of things you will find in homes/offices of people who buy a computer from some big store because they want to run common programs. Historically, that meant x86/amd64. Lately, a surge of consumer grade ARM devices is changing that somewhat. I am not aware of any HPPA ever being sold to an end user who "just wants a computer" and has no idea that the exotic architectures even exist.

I'd like to hear some feedback about C36xx, C37xx and c8000.

any one?

first attempt of booting kernel v3.10.95 failed
I compiled the kernel using arch/parisc/config/c3000
but the kernel is not booting, and no message on the serial console @____@

I have replaced with my 2.6.29, and I am again on the console.
