As someone from Oxford Semiconductor kindly posted at linux1394-user, the way to properly detect chip and firmware of OxSemi based devices is to read at a certain offset from the configuration ROM. This can be done for example - with gscanbus: Click on the device icon to see its "Physical ID". Use the menu "Transactions/ Read Quadlet". In the dialogue, enter the ID as destination and 0xFFFFF0050000 as memory offset and hit OK. A result should appear in the third text box. - with 1394commander: Enter the command : i to get some basic information about the bus. Guess the disk's physical ID from it or from syslog. Enter the command : r . # 0xFFFFF0050000 4 with # replaced by the disk's physical ID (e.g. 0 if there are only two nodes and the local node has ID 1). A success message and 4 read bytes should appear. We would need the thereby obtained value from affected firmwares, and ideally also from unaffected firmwares to cross-check. Then it is possible to add some code to sbp2 to warn about these devices or perhaps even activate a workaround to avoid the "SCSI error... Logical block address out of range", in case there is such a workaround. I have one enclosure with OXFW911 which does not show the signs you described. It's magic number is 0x88000731. The last byte, 31, is firmware revision information, all other bytes denote the chip type OXFW911. But that said, I would rather like somebody wrote a Linux utility for firmware uploads than to add these workarounds to the kernel driver. That would of course require additional information from Oxford Semiconductor (and from any other SBP-2 bridge manufacturer whose chips we wanted to support). BTW, the problem with Oxford chips under OS X 10.3 was about OXUF922 (FireWire 800 bridge), not the OXFW911. Furthermore, the "sbp2: aborting sbp2 command" during later disk access may be unrelated to the initial "SCSI error... Logical block address out of range" and may be a driver bug instead of a firmware bug. There are conceptual problems in sbp2 which I hope to resolve eventually. (Don't hold your breath, I am already half a year behind my plans with sbp2 due to lack of time.) A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you. (this is a mass-close to kernel bugs in NEEDINFO state) As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue still occurs for you and I will try to assist in its resolution. Thank you for taking the time to report the initial bug. If you believe that this bug was closed in error, please feel free to reopen this bug. |
