Latest working kernel version: 2.6.23.16 Earliest failing kernel version: 2.6.24 Distribution: Debian stable Hardware Environment: Pentium 4 (HT) Software Environment: Debian stable/ kaffeine 0.8.5 Problem Description: Hello, I have very bad problem with kernels above 2.6.24. Till my last working kernel 2.6.23.16 DVB-T playing with kaffeine worked like a charm with many different USB dongles. After upgrade to 2.6.24 and all above versions kernel crashes in random time playing DVB. I tried switch off HT, but it didn't help. I tried bisect between 2.6.23 and 2.6.24 but without success - in first iteration kernel failed to compile. I also tried 2.6.25.4 with latest linuxtv.org git version, also crashes in one minute...and finally I see same behaviour with different dongles using different kernel drivers - but when I move back to 2.6.23, all of them works for infinite time (2 weaks in row) - so this isn't HW problem and it is not HW specific problem... Can anybody help me find/track the problem? tata:/boot# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.40GHz stepping : 9 cpu MHz : 1200.000 cache size : 512 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe up pebs bts cid xtpr bogomips : 4800.13 clflush size : 64 tata:/boot# lsusb Bus 008 Device 002: ID 0db0:697a Micro Star International Bluetooth Dongle Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 0458:0003 KYE Systems Corp.

Could you provide us more info, including what's the affected driver and post also the OOPS log?
Hello, as I mentioned it happens with every driver I can test (dib3000, dib7700p, pluto2) so for me it looks like somewhere in layer above it. I don't have any oops, kernel simply freezes and only reset button si way for me (no ping from second computer)
hardware ? Can you duplicate it on multiple PCs ?
This doesn't happen again. Bu there is other problem in 2.6.32 kernel see: http://bugzilla.kernel.org/show_bug.cgi?id=15016
