most likely this just "appears" as 2-way processor , but iŽm quite sure this is just a single-core CPU, but with HyperThreading enabled.

Hello,
I've been having consistent hard system freezes for a

long time, every 2 days or so, and finally decided to

move to the most recent stable kernel. Unfortunatelly

that didn't fix it. The freezes seem to be io-related;

they started since I moved my drive to sata. They seem

to happen mostly when there's an io-intensive operation,

like extracting a big archive; a reboot is needed.
Nothing ever shows up in the logs.
I'm using the following drive:
ATA device, with non-removable media

        Model Number:       MAXTOR STM3160215AS

        Serial Number:      6RA2TMJ4

        Firmware Revision:  3.AAD   
Linux localhost 2.6.24.4 #4 SMP Fri Mar 28 14:51:50 BRT 2008 i686 GNU/Linux
This is a 2-processor CPU:
# cat /proc/cpuinfo

processor       : 0

vendor_id       : GenuineIntel

cpu family      : 15

model           : 4

model name      : Intel(R) Pentium(R) 4 CPU 3.00GHz

stepping        : 9

cpu MHz         : 3013.697

cache size      : 1024 KB
(same goes for processor : 1)
Sincerely,

Hello all,
Thanks to valuable help from roland, I was able to

boot with the following options:
``nosmp ide=nodma libata.dma=0''
after what I ran an agressive stability test for a

while, with no problem whatsoever. Maybe it's too

soon to say, but I have a good feeling this time. It

seems roland figured it out.
If everything goes well, I'll reduce the command line

in order to narrow the problem further down.
(and indeed, this is a hyper-threading single core CPU)
Sincerely,
