<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <tt>Hi Badari,</tt><tt></tt> <tt>Just to be clear, you stated:</tt> <blockquote TYPE=CITE> <pre><tt>crash -d1 shows me crash: get_netdump_panic_task: crashing_cpu: 1 crash: get_netdump_panic_task: failed crash: get_active_set_panic_task: failed</tt></pre> </blockquote> <tt></tt> <tt>and I presumed:</tt> <tt></tt> <blockquote TYPE=CITE> <pre><tt>Now, since after the "crash: get_active_set_panic_task: failed" message, there are no more error messages, so panic_search() must have determined that the idle thread (swapper) on cpu 0 was in fact the running task that took the sysrq.</tt></pre> </blockquote> <tt></tt> <tt>But, are there any other error messages after the</tt> <tt>"get_active_set_panic_task: failed"? Like for</tt> <tt>example:</tt><tt></tt> <tt> crash: panic_search: failed (via foreach bt)</tt> <tt> crash: get_panic_context: panic task not found</tt><tt></tt> <tt>or did you see:</tt><tt></tt> <tt> crash: panic_search: ffffffff80335340 (via foreach bt)</tt><tt></tt> <tt>Thanks,</tt> <tt> Dave</tt></html>
