Then I get what I term as "udev hell". That is when FC6 gets to the point during boot-up of saying "Starting udev: " and hangs for about 5 minutes and then continues. I don't think my log records what happens in that elongated pause. Later attempts to talk to the single SAS disk (one port only connected) during boot-up are shown below starting from the first sign of trouble. The SAS address of the disk port is 0x5000c50001b02139 . > Or even try the other expander? Same as yesterday's report: sas: RG to ex 500605b000000af0 failed:0xffffff06 If I fiddle with the cabling long enough (i.e. shorten it) then it will work some of the time. But how come the card POST, Luben's driver and Adaptec's for Windows have no problem with exactly the same wiring all of the time? I suspect that either the HBA's phys are not being set up properly or, the first blemish (e.g. loss of dword synchronization) on the link, knocks the production driver off its perch, while the other drivers recover and continue.
