Summary: machine check handler can deadlock
Kernel Version: all 2.4, 2.5
Status: NEW
Severity: normal
Owner: mbligh@aracnet.com
Submitter: ak@suse.de

The machine check handler calls printk but does not honour cli/sti. When an MCE
happens inside a critical section of printk it'll deadlock.

(bug is in x86-64 too, probably other platforms)
