Hi, I can reproduce this problem on my SS20 UP (TMS390Z50) using a tape drive. I've been testing 2.6.13 and 2.6.16-rc2, with the tape on ESP100A-FAST and ESP236-FAST. I test using tar and the 'btape ... test' commands. One thing I have noticed is that I only get the error while reading, so far it has never happened while writing.
The exact error I'm getting is: esp1: DMA error 4004430e esp1: Resetting scsi bus esp1: SCSI bus reset interrupt st0: Error 80000 (sugg. bt 0x0, driver bt 0x0, host bt 0x8). esp1: Warning, live target 0 not responding to selection. st0: Error 60000 (sugg. bt 0x0, driver bt 0x0, host bt 0x6). esp1: Warning, live target 0 not responding to selection. This has only happened to me twice using just hard disk activity, under extreme circumstances. Extreme meaning after it had run out of both memory and swap space. My 2 hard disks are attached to the ESP100A-FAST. When I attach my tape there and trigger the problem, the hards disks also get the "not responding to selection" errors. So the whole controller is affected. Some questions: 1) Kernel bug 6344 mentiones the last working kernel is 2.4.32. Does anyone have this working with a later kernel? 2) Are there known changes in the dma/sbus area? Is there any merrit trying later kernels? 3) Is there any way to correct the situation? I have to reboot it to start from fresh. Removing/adding the device using /proc/scsi/scsi does not help. I plan to try the eh locking patch posted next, and maybe something like 2.6.8 after that if it is still not working. Unless someone has a better proposal.
