Dell CERC Adapter hangs temporarily until reset. REGRESSION
Status in linux package in Ubuntu:
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 have changed PCI interrupts around and moved card slots to minimize sharing and removed cards - repeatedly.
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 have tried all combinations of card RAID options Read ahead, Write cache, and other BIOS options.
Relevant dmesg lines (these were consecutive):
