Dell PowerEdge M610 and M710 systems are certified for RHEL5.3 (and RHEL6). When installing RHEL5.4 (and RHEL5.5, 5.6), a panic is logged:

BUG: warning at drivers/base/core.c:101/device_release() (Tainted: G )

Comment 3 Derrich Hafemann 2011-04-11 20:12:19 UTC 
These kernel panics are happening on RHEL 5.4, 5.5, 5.6 but not the 20110409.3 build of RHEL5.7.
Comment 4 Prarit Bhargava 2011-04-18 14:41:44 UTC 
Not a panic.  Just a warning.

CLOSED/NOTABUG ... works in latest tree.
