Let me check if I can get access to an HP rx8640 to re-spin the patch. -----Original Message----- From: Alex Chiang [mailto:achiang@xxxxxx] Sent: Tuesday, January 12, 2010 3:58 AM To: Yu, Luming; Luck, Tony Cc: linux-ia64@xxxxxxxxxxxxxxx Subject: lockdep support caused an MCA This patch 2f02b4a12b24c9f077c6d739ac23c9b90840ccca: Author: Luming Yu <luming.yu@xxxxxxxxx> 2009-12-04 09:14:30 [IA64] lockdep support Basic functionality for lockdep on ia64. Known issues: 0. dynamic allocate per CPU area in lockdep. 1. lock held in leave kernel. 2. enabling CONFIG_DEBUG_LOCKDEP triggers the lockdep warning. 3. Need to implement save_stack functions 4. Replace some cpp macros with inline functions 5. Add nmi_enter/nmi_exit Signed-off-by: Bob Picco <bob.picco@xxxxxx> Signed-off-by: Yu Luming <luming.yu@xxxxxxxxx> Signed-off-by: Tony Luck <tony.luck@xxxxxxxxx> causes a very early MCA on an HP rx8640. Unfortunately, even with early_printk turned on, the machine encounters the MCA and reboots before any output occurs, so I don't have any further information. I haven't done any other triage on this as the patch has already been dropped from Tony's tree, but I'd be happy to test the next go-around.
