I see panics during boot with the last two FC4 kernel updates on a dual Opteron 248 Sun V20z (2 146GB SCSI drives). From watching the log messages it seems to be correlated with mounting the SCSI partitions towards the latter end of the boot phase -- I'd gladly post the boot log if it's relevant and someone can tell me how to recover that log after re-booting successfully with the 1369 kernel.

Anyone else seeing this and/or have any information/pointers/hints to offer?
