Hi, We found a hard hang on a HP x86 system installed snv_130. firstly I add "set snooping=1" to /etc/system to try to get a core dump file. but it doesn't work, the system hang more than one hour and can't enter kmdb mode (the deadman timer is the default value). secondly I add?set pcpslump:apic_panic_on_nmi=1? to /etc/system, and send an NMI to OS from HP utility, The system enters the kmdb mode this time, But the keyboard freeze and I am not able to perform any operations in kmdb.
Does anyone know any other way to debug this hard hang? Thanks, Colin -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.opensolaris.org/pipermail/mdb-discuss/attachments/20100222/c83ac739/attachment.html>
