Most recent kernel where this bug did *NOT* occur: 2.6.16.31 with xen 3.0.2 patches Distribution: ubuntu, first dapper now edgy Hardware Environment: msi s270 laptop with turion MT-40 cpu Software Environment: allround laptop running kubuntu Problem Description: kernel crashs - screen turns white (or other color or stripes), is not pingable, nothing in syslog or netconsole. does not happen with xen'ified kernel, but happends with all vanilla kernels I tried (tried at least 2.6.15+). does not happen with memtest86+. does not happen while compiling only (cpu stress) or watching videos. but does happen very fast with gui apps like konqueror, firefox, thunderbird, kontakt etc. Steps to reproduce: boot, login, run gui app for a few minutes till crash. I also documented this with all config files, dmesg etc here: http://www.megawiki.org/wiki/S270Crashing If you prefer I can attach all files here too.
