Care to point me to more information about this? https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227893 (and a bunch of dupes), and also in your inbox on 19th March, with subject "sysfs use-after-free in 2.6.21-rc" > > It's not the _correct_ fix, because the crash is just a _symptom_ of the > > fact that somewhere in that sysfs mess we have a pointer to freed > > memory.

We've been seeing it ever since we enabled CONFIG_SYSFS_DEPRECATED about 2.6.20-rc6-git1. For the moment I've committed a hack to disable the extra variables in uevents, since that wasn't why we turned SYSFS_DEPRECATED on again anyway. It's not a fix though. -- dwmw2 -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
