Hi, With FC-6 I have been seeing a lot of soft lockups with all shipped kernels on my Dell x86_64 SMP machines. For example, inserting a USB key triggers a soft lockup, as does the VMWare bridged interface. I realize the latter taints the kernel, but the former happens with untainted FC-6 kernels (i.e. the vmware stuff not installed let alone loaded). Anyway, I have reported bugs, detailing the stack trace that pops up in dmesg, but I get the feeling this isn''t that helpful for debugging. So, my general question is this: What extra things could I do to provide more information about soft lockups? Best wishes, Jonathan

Try removing the SanDisk "value-added" DRM crap. See the latest bugzilla entry for details.

Actually you''ve done well, it just needs looking at the code which I haven''t done due to... oh, look, something shiny! It''s the RHEL-3 U9 and a monkey with Avocet Hi-Speed USB dongle! -- Pete
