Hi, I have re-occurring oopses and panics in those above kernels. The error is always the same. I have the last Kernel Panic as a picture here: http://dev.tequila.jp/clemens/R0010172.JPG The oops have the same error style like this Panic. I tried to capture one, but right after copying it into vim, I got a Panic. So next time I try to. I think it started with 2.6.19.2, I cannot remember I had any of those problems before. The box can work fine for about a week or more, or it looks up several times a day. I run a memtest for 10 h, but I had no errors. attached are config files for the above three mentioned kernels. -- [ Clemens Schwaighofer -----=====:::::~ ] [ TEQUILA\ Japan IT Group ] [ 6-17-2 Ginza Chuo-ku, Tokyo 104-8167, JAPAN ] [ Tel: +81-(0)3-3545-7703 Fax: +81-(0)3-3545-7343 ] [ http://www.tequila.co.jp ]
