I have seen many of these messages here on a system that I just
upgraded to 2.0.5 and a Pentium-100 (I placed a copy of one
representative example at the end of this note). Previously, under
1.1.5.1 using 3 BusLogic BT-747S controllers and 486DX4/100, all
15 of disk drives were happy...system would run for weeks w/o
incident and I had *no* disk problems. Now, with the current
configuration:
100MHz Pentium, Triton chipset, 256KB cache, 32MB DRAM
4 NCR 53C810 PCI SCSI controllers
1 disk, 2 tape drives, 2 CDROM drives on first controller internal
Remaining disks in an external box, divided among each of the
remaining controllers
5 of my disks that previously worked will not work with this configuration.
They are:
3 QUANTUM PD700S 3110 (these drives work when internal w/short cables)
1 DEC DSP3105S X385
1 TOSHIBA MK438FB 5133
The remaining working disks are:
1 MICROP 2217-15MZ1001901 HZ30 (internally mounted root volume)
4 DEC DSP3105S 386C
1 C2247-300 0BE4
2 DEC DSP3210S 435E
1 SEAGATE ST12550N 0013
1 SEAGATE ST12550N 0014
I tried various combinations of different drives on different busses
to no avail. Note that termination and ID assignments are correct.
I considered connecting my SCSI bus analyzer up to see if I could
get a clue to what was going wrong from the bus activity but ran
out of time. (This is my primary server and it had been down a
long time already.)
A sample error message:
assertion "cp == np->header.cp" failed: file "../../pci/ncr.c", line 5235
assertion "cp" failed: file "../../pci/ncr.c", line 5236
ncr1 targ 4?: ERROR (80:100) (e-ae-0) (8/13) @ (10d4:e000000).
