Description Bastien Nocera 2005-10-20 10:23:45 UTC
In arch/x86-64/kernel/bluesmoke.c: __setup("mce", mcheck_enable); And the comment for mcheck_enable says: /* mce=off disable machine check mce=nok8 disable k8 specific features mce=disable<NUMBER> disable bank NUMBER mce=enable<NUMBER> enable bank number mce=NUMBER mcheck timer interval number seconds. Can be also comma separated in a single mce= */ But the '=' passed to mcheck_enable is not taken into account, and parsing will fail every time. Trivial patch attached.

Comment 2 Jim Paradis 2006-02-10 18:53:43 UTC
This bug, as reported, is actually against RHEL3, not RHEL4 (the patch supplied is a 2.4 patch, and bluesmoke.c is only seen in RHEL3). The same problem occurs in RHEL4, though. I'll file a separate bug for that.
Comment 3 Ernie Petrides 2006-02-18 00:25:30 UTC
A fix for this problem has just been committed to the RHEL3 U8 patch pool this evening (in kernel version 2.4.21-40.2.EL).
Comment 4 Ernie Petrides 2006-04-28 21:53:20 UTC
Adding a couple dozen bugs to CanFix list so I can complete the stupid advisory.
