It fails consistently here on Intel R440LX server motherboards with built
in 7880 chips and seagate cheetah disks (all the 5.1.0-pre drivers have
had some problems on these I think), I only have this configuration on
production systems here so I cannot test new drivers very often.
The system works fine with a 2.1.117 kernel and driver version
5.0.20 (as defined by AIC7XXX_C_VERSION in aic7xxx.c).
If you have some speficic things you want me to try I'll try to get it
done today or tomorrow.
Tested configuration: 2.1.124-pre2 with 5.1.0-pre14 driver,
Intel R-440LX motherboard, no additional cards (built-in scsi & ethernet),
a single PII/300 with 384m ram, one single Seagate Cheetah disk on the
system.
These error messages were logged (it actually managed to write them to
disk, so the system isn't entirely dead, but during each scsi hang the
system is dead for just over 15 seconds, ie no response to ping,
and the hangs happen VERY frequently).
Fist, the stuff logged at boot:
