Hi,
since yesterday a new bios update 05CU for the N140 is available at the german samsung page:
Hope this will fix the freezes under linux…

[/quote1263658829]I haven’t tried the new firmware yet, so it may indeed fix the Linux freezes, but you may be interested to know that there are some experimental kernel fixes available for some distros which appear to fix the issue.
For Ubuntu, voria has created an experimental kernel package with the fix for testing – I’ve tried this and it appears to have fixed the issue for me at least – see this thread: http://www.voria.org/forum/viewtopic.php?f=3&t=358
For Arch Linux, I haven’t tried it, there are instructions for installing a kernel with the appropriate patch on this page: http://wiki.archlinux.org/index.php/Samsung_N140
Hope it helps,
MattPS. If anyone has info as to whether the firware fixes the freezes or not then that would be useful to know…
The new version was posted at the samsung.com homepage too:

[/quote1263659446]I use the latest 2.6.32-5 kernel from debian unstable, which doesn’t fix this problem. :-/
FYI, I’ve updated to this latest BIOS – update process was fine and smooth.
Fish.666: sorry to say that the new BIOS does not fix the Linux hangs. I tested with a live ubuntu distro and that hang is still there, so it seems that the patched kernels are the only way to resolve the issue at the moment.

Ok, thanks for this information. At the moment i’m building a custom kernel with this fix and the other backlight fix from here:

[/quote1263663691]FYI, I believe that the patch which has been applied to the Ubuntu and Arch test kernels for this issue is this one: http://marc.info/?l=linux-ide&m=122724081603679&w=2 You ought to be able to apply that to a debian kernel to try and fix it there too.

I’m building the kernel with the patch piix-spurious-irq.patch from here:
