Summary: kernel oops with radeon and mythfrontend Kernel Version: 2.6.18-rc2 Status: NEW Severity: normal Owner: [EMAIL PROTECTED] Submitter: [EMAIL PROTECTED] Most recent kernel where this bug did not occur: 2.6.15.5 Distribution: debian Hardware Environment: IBM Thinkpad R50, ATI Radeon Mobility 9000 M9, Wideview DVB-T USB Software Environment: mythtv 0.19-0.10, xorg 7.0.22 Problem Description: I am getting the kernel oops shown below, when trying to watch live-TV or recordings with mythfrontend. I tried with different pre-compiled mythtv binaries on a debian linux (0.19-0.6sarge1, 0.19-0.7 and 0.19-0.10), with vanilla kernels 2.6.17.4 and 2.6.18-rc2. The oops doesn't occur with a 2.6.15.5 kernel.
