[LAU] ssh problem, with ubuntu realtime kernel

Hi I recently switched to ubuntu (from debian) and for the most parts I'm doing ok. However when running the realtime kernel (that's part of ubuntu, I think I simply imstalled it by "apt-get install linux-image-rt linux-restricted-modules-rt") the computer completely freezes (not even accepting incomming ssh) when copying larger files with scp. Very small files are ok, just now it died on my with a 8M file. I'm running the ath_pci module from restricted modules for my wlan card, and the problem is not there when booting into the unpatched, regular ubuntu kernel. Anyone heard of something like this? Any solutions? Where to file a bugreport? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
