I forgot to add that although this is booted from the PXE at this time, I have previously installed and updated the 15.10. I have tested both 32 and 64 bit versions with identical results, the server now has exactly 4G RAM (4x1GBxREGECC). 14.04LTS is currently installed as 2nd OS on HD, but it has a PCI NVIDIA card so the video doesn't work right (missing icons/menus/text in lists when moused over). I'm hoping the 16.04LTS will solve both issues simultaneously. Both the 32 and 64 bit versions of 14.04LTS and earlier work OK.
The user is trying to use this server as a desktop workstation, so the onboard video isn't good enough, which is why it has the PCI card, it used to have 2 PCI video cards when he required DVI output because the BIOS won't recognize most cards, so no video until OS was booted. I have tried removing the PCI wireless also, which is the last remaining other card. I do not specifically remember trying the drives with the onboard video only, but since it didn't matter if the interrupt was tied to the same line or not (tried in 2 different slots), I doubt that would make a difference.

REGRESSION Status in linux package in Ubuntu: New Bug description: The HD CERC SATA 1.5 RAID controller (PCI-64 slot) hangs regularly for 10-60 seconds until reset. The CERC card firmware is the newest I can find reference to: 4.1-0 [bld 7419]. The Dell Poweredge 1800 has newest BIOS (A07). All hardware has been tested thoroughly OK except possibly the APIC component (Serverset Northbridge?). The 14.04LTS with all updates (or not) works fine with a perfectly consistent throughput of 77MB/s (slowest HD=66MB/s), RAID5. 15.10 has the hangs of 10-60 seconds, AND with newest updates as of 26-FEB-2016. I do not have a 14.10 or 15.04 to test that I can get to boot on this system. I have changed PCI interrupts around and moved card slots to minimize sharing and removed cards - repeatedly. (It may not be possible to disable enough devices to completely avoid interrupt sharing). All hard drives and cables have been thoroughly tested, but the drives are mixed: 1 of 66MB/s, 1 of 125 MB/s, and 3 of 100MB/s. The drives not only work perfectly in 14.04LTS, but all Windows versions and DOS/BIOS-INT 19 as well (0x13). I believe I tried in Ubuntu 9.10 as well, but am only 85% certain. If I did, it worked fine. I have tried all combinations of card RAID options Read ahead, Write cache, and other BIOS options. Relevant dmesg lines (these were consecutive): [ 1046.808027] aacraid: Host adapter abort request (4,0,0,0) [ 1046.808123] aacraid: Host adapter reset request. SCSI hang ? [ 1297.828038] aacraid: Host adapter abort request (4,0,0,0) [ 1297.828168] aacraid: Host adapter reset request. SCSI hang ? I run a repair shop, so I may not have access to the server for very long. It's getting Windows reinstalled after RAM went bad and was replaced (and again, thoroughly tested through CPU and DMA channels (though not as through DMA)).
