I've installed this patch on 3 differents machines there status after
about 12hours:
- SUN FIRE X4170 M2 (amd64: r255178) with 6 SAS harddrives in one big
zraid (LSI MegaSAS Gen2 controller): Used for generating package with
poudriere… no probleme since;
- HAL/Fujitsu SPARC64-V (sparc64: r255178) with two SCSI-3 disks in
gmirror: Used for generating package with poudriere too… no probleme
since;
- HP EliteBook 8460p (amd64: r255188) with DVD replaced by a second
hardrive (where fbsd is installed): It crash just after the message
"GEOM: new disk ada1" during boot
