Description Problems with detecting hardware such as SCSI cards, LAN cards (Linux system-specific).
Explanation Problems when using an ASUS PR-DL533 motherboard: Linux does not detect hardware
correctly. It is a known problem of the Linux ACPI subsystem that it does not work correctly with
some motherboards. If specifying the general acpi=off option, it is possible that the ACPI
subsystem does not detect the hardware (on-board network card, SCSI card) correctly.
Workaround Specify the following boot parameters:
acpi=oldboot pci=noacpi apm=power-off
Description If you check for potential inconsistencies between a File System Catalog (FSC) and Fast
Recovery Information (FRI) data on the corresponding FSE media, the following lines may be
present in the output of the fsecheck --fsc-media command:
DUMP: FSC FRI Notes
MigSize SizeInFSC SizeInFRI MISMATCH
MigFlags FlagsInFSC FlagsInFRI MISMATCH
The MISMATCH keywords indicate inconsistencies. After you invoke the command fsecheck
--fsc-media --autocorrect to solve the underlying problems, these inconsistencies are
not resolved.
Explanation Corrupted FRI on the FSE media prevents the inconsistencies from being resolved. You have to
recreate the FRI on the FSE media first.
Workaround Proceed as follows:
1. Run the following for each FSE medium that belongs to the problematic FSE partition:
fsemedium --recreate-fri Barcode
2. Invoke fsecheck --fsc-media again, specifying the --autocorrect option to
enable automatic correction of inconsistencies in the FSC:
fsecheck --fsc-media --autocorrect PartitionName
