I'm posting this to both lists as a matter of interest, my apologies to whoever should not be reading this. I recently installed an off-board IDE controller to manage a large hard drive in my system. FreeBSD has been exhibiting some rather unsettling instabilities, which usually culminate in a kernel panic. Upon reboot after the panic, all the file systems on the drive in question have hundreds of softupdate inconsistencies. I searched the mailing list archives and found a similar bug involved with striped vinum volumes and unmounting after heavy I/O. I have encountered the bug with the GENERIC kernel included with FreeBSD 4.5-RELEASE, and all 4.5-STABLE kernels I have built after installation. It only seems to occur when the drive is handling heavy I/O operations, notably during a make world, or a large file copy, and even once when I recursively changed ownership for an entire directory in /usr/home. (The drive handles all filesystems except /) The IDE controller is a CMD-649 PCI ATA-100 controller. CMD state on their web site that they do not provide end-user support or hardware. The hardware vendor, STLab, does not seem to exist. Have I been looking in the wrong place, or simply not looking hard enough, is this a known bug and if so how can I fix it?
