Subject: NMI watchdog detected lockup
Date: Sun, 17 Oct 2004 15:58:37 -0700 [thread overview]
Message-ID: <4172F91D.8090109@osdl.org> (raw)
I'm seeing this often during a kernel build on AIC79xx.
I did one kernel build on SATA without seeing this.
This is on a dual-Opteron IBM Workstation A with
2 GB RAM, SATA, & SCSI.
Does this show anything? (not to me)
Maybe the buggy code is on CPU1 and its registers aren't
captured.
