Subject: MCA/INIT debug trace
Date: Thu, 10 Aug 2006 09:27:02 +0000 [thread overview]
Message-ID: <44DAFBE6.4030701@bull.net> (raw)
Hi Keith and all,
a few days ago, I have tried to debug some deadlock problems
occurring on an IA-64 machine using INIT signal.
I have noticed that only the blocked process backtraces are shown on the
console screen
and the general registers are not displayed anymore.
To improve it, could it be possible to integrate the following patch
here below ?
I have just added a call to "show_regs" in
"ia64_mca_modify_original_stack" function.
Regards,
Francois
