tapjpa, here is the relevant line from my /proc/cpuinfo:

Processor: Intel XScale-PXA255 rev 6 ( v51)

Guest/Brad who was asking about how to run cat /proc/cpuinfo from the terminal, you must have the terminal package installed; it did not come installed by default in my 5600. I got it from the Zaurus Software Index but it is also available on the CD that came with the 5600. Once it\'s installed, open a terminal from your apps menu, then at the prompt

bash-2.05$

type the line:

cat /proc/cpuinfo

The processor info should be in the first line of the file. Type exit to exit the terminal.

I got one from amazon its got the 250 cpu. I havent started pushing it yet but havent noticed any issues. What exaclty are these bugs?

Are we talking bad productions rates (then an non issue for the end user) or are we talking about a cpu rev (unlikely as that would have meant a major retest and incompatible software??)

I\'m totally happy with my purchase, its met all my expectations and then some. Be objective with what youve got and the desire for the \'next model up\' syndrome

I also got a Zaurus SL-5600 from Amazon this week. Box and System Info say PXA250....

The bug in the PXA250 CPU could potentially cause some memory corruption, which would like lead to a crash. They made a workaround in the PXA250 5600 kernel to ensure this never happens, although the effect of the workaround is that the PXA250 5600 runs at half the speed it should.

But like I have said, the kernels here http://www.zaurususergroup.com/modules.php...download&sid=53 have this workaround turned off and let the PXA250 5600 run at the full 400MHz and no one has reported any instability.

i highly doubt sharp would spend the resources to drop in a 255 in a 5600

They had no choice. Intel stopped producing the PXA250.

Hey how about a class action suit against Intel to replace them...

As another data point or two, my brother-in-law got one from Amazon.com a week ago, don\'t know which warehouse, but it went to Houston, and has a PXA250.

I just received mine from HSN.com (no, they don\'t have any more, sold out 1200 in about 10 minutes), with the camera for the same price as Amazon. It\'s a PXA255, according to both the box and /proc/cpuinfo

The SL-6000 must be coming out soon. They had a firesale like this for the SL-5500 just before bringing out the SL-5600, which was even more secret than the SL-6000. To top it off, I got a tip from a UK retailer that there was news of a new Zaurus in the UK! I\'m going to see if I can pry a model number out of them

Anyway, I guess Sharp had no choice in swaping to the PXA255. Though I could well imagine that if Sharp still had stock of the PXA250 they would not have changed it, especially since it looks so close to a new model coming out.

I purchased one of the SL5600\'s from Amazon. It came
with the PA250. Another data point.

Hey All,

So I just bought a 5600 from Amazon last week and it has the pxa250 processor, it says on the box and in /proc/cpuinfo.. This thing rocks though!

Previously I had an ipaq 5455 which was garbage. I bought it for wireless networking and soon realized it was woefully inadequate. The Z is way faster than the ipaq, the browser most notably. I know it\'s apples to oranges, but the Z just feels quicker, and probably is.

I\'ve been using the thing all week for kismet wifi sniffing, games, web surfing, and email and I haven\'t had any problems or even one crash. Updated to the 1.32 Sharp ROM also.

So, for us noobs, what\'s this bug with the 250\'s and how to avoid it?

The specs on the sl-5600 say pxa250 400mhz processor on the web for this. Read zdnet as well (see below). I doubt that they changed the processor in the development of the same unit.

From zdnet:

The SL-5600 uses a 400MHz Intel PXA250 XScale processor, not the low-voltage PXA255, which has a faster CPU bus and uses less power. With 32MB of SDRAM and 64MB of flash memory, the Zaurus gives you plenty of room to work in. Taking about 3 seconds to start or close programs, we were able to back up the system in 2 minutes and restore it in 3 minutes, 15 seconds, including restarting the system.

Sharp didn\'t have an option, Intel stopped making the pxa250. Sharp would either have to switch to the pxa255, or stop manufactuirng of the 5600.
