IŽve been punnishing the system with heavy swapping, both with
2.0.33+aic-5.0.[78] and 2.1.90-pre3+aic-5.0.7.
IŽve made the tests with swap on and off, with both kernels. Remapping
bits were on.
Swap off
--------
No problems with any of them. It looks like the swap partition has got
physical errors, as I donŽt get failures without swap.
Swap on
-------
2.0.33 recovers from errors, but other partitions in the same drive
start failing when swap starts.
2.1.90-pre doesnŽt recover from all the errors and finally the system
locks up; iŽts not a hrd lock as I can use the magic keys, but I canŽt
even shutdown the machine.
My conclusions
--------------
ThereŽs something wrong in the SCSI error recovery in 2.1.89 and
greater kernels.
IŽll turn on debugging this midday, with 2.1.90-pre3 and see what I get.
Thanks for your interest.
