I had win XP and open SUSE installed on hd1 with, Debian installed on hd3 and hd2 as a 'go between' for data between systems/OSs. I can only think that because I installed win 7 (possibly a contraband install) to determine issues I had with my sat-nav that 'booting issues' ensued. I 'quick formated' hd2 and perhaps this should've been a 'long format' to show any bad sectors, but other issues may arrise. Best regards, Ray Dart. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Content of s_kcrashErrorMessage: [Current thread is 1 (Thread 0xb2e299c0 (LWP 1679))] [KCrash Handler] #8 0xb7f63549 in __kernel_vsyscall () #9 0xb5327b14 in __libc_signal_restore_set (set=0xbf8293cc) at ../sysdeps/unix/sysv/linux/internal-signals.h:105 #10 __GI_raise (sig=6) at ../sysdeps/unix/sysv/linux/raise.c:47 #11 0xb531030d in __GI_abort () at abort.c:79 #12 0xb57920ce in qt_message_fatal (message=<synthetic pointer>..., context=...) at global/qlogging.cpp:1914 #13 QMessageLogger::fatal (this=0xbf829678, msg=0xac8c5dc0 "QSGSimpleMaterialShader does not implement 'uniform lowp float %s' in its fragment shader") at global/qlogging.cpp:893 #14 0xac89113c in QSGSimpleMaterialShader<FadingMaterialState>::initialize (this=<optimized out>) at /usr/include/qt5/QtQuick/qsgsimplematerial.h:66 #15 FadingMaterialShader::initialize (this=0xb0409170) at /usr/src/debug/plasma-framework-5.85.0-2.1.i386/src/declarativeimports/core/fadingnode.cpp:77 #16 0xb75d4ef1 in QSGBatchRenderer::ShaderManager::prepareMaterial (this=0x291c4d0, material=0x385e5b0, enableRhiShaders=false, geometry=0x0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:306 #17 0xb75dbd9e in QSGBatchRenderer::Renderer::renderMergedBatch (batch=<optimized out>, this=0x2ae4ee0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:3082 #18 QSGBatchRenderer::Renderer::renderMergedBatch (this=0x2ae4ee0, batch=0x3893bf0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:3026 #19 0xb75e17fa in QSGBatchRenderer::Renderer::renderBatches (this=0x2ae4ee0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:4066 #20 0xb75e20b8 in QSGBatchRenderer::Renderer::render (this=0x2ae4ee0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:4363 #21 0xb75c8aeb in QSGRenderer::renderScene (bindable=warning: RTTI symbol for class 'QSGRenderer::renderScene(unsigned int)::B' is not a type ..., this=0x2ae4ee0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgrenderer.cpp:264 #22 QSGRenderer::renderScene (this=0x2ae4ee0, bindable=warning: RTTI symbol for class 'QSGRenderer::renderScene(unsigned int)::B' is not a type ...) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgrenderer.cpp:220 #23 0xb75c9082 in QSGRenderer::renderScene (this=0x2ae4ee0, fboId=0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/coreapi/qsgrenderer.cpp:212 #24 0xb76328aa in QSGDefaultRenderContext::renderNextFrame (this=0x186eed0, renderer=0x2ae4ee0, fboId=0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/qsgdefaultrendercontext.cpp:228 #25 0xb76a53c9 in QQuickWindowPrivate::renderSceneGraph (this=0x19d95e0, size=..., surfaceSize=...) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/items/qquickwindow.cpp:617 #26 0xb761c908 in QSGGuiThreadRenderLoop::renderWindow (this=0x1848780, window=<optimized out>) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/scenegraph/qsgrenderloop.cpp:763 #27 0xb76b5270 in QQuickWindow::event (this=0x174cb50, e=0xbf82a610) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde29-1.3.i386/src/quick/items/qquickwindow.cpp:1858 #28 0x004f25ba in ??
