Motherboard : portwell robo578 - AMD K6-2 300Mhz - RAM 96 - onboard Adaptec AIC7880 - onboard intel 82558 ethernet chip 10/100 SCSI BIOS ENABLED 20mb flash-card (ide) as boot/root disk (I've also tryied using a 'normal' hard-disk but nothing changes) External Scsi Devices : Redundant Raid Controller CMD CRD5641 4 seagate disks in a single raid-5 raid-set OS : linux 2.0.37 ipnat patched + integrated aic7xxx (version 5.1.13) and eepro100 Task: nfsd exports a 4Gb ext2 scsi disk partition, servicing a network client. A test program on the client is always writing/deleting a recursive copy The active scsi transfer rate is 20mbps symptom : after 4 hours of continuos data transfer , the system starts displaying the following messages on the console : *date* localhost kernel: scsi: aborting command due to timeout: pid x, scsi0, channel 0, id 0, lun 0 0x28 00 01 53 28 00 00 02 00 *date* localhost kernel: SCSI host 0 abort (pid xxx) timeout - resetting *date* localhost kernel: SCSI bus is being reset for host 0 channel 0 *date* localhost kernel: scsi: aborting command due to timeout .... The message repeats every few seconds and - after an arbitrary period of instability - the kernel freezes. No data transfer can be done in the meanwhile aic7xxx options are default (5 sec. delay) If I reset the motherboard (not the CMD) system is back to fine working for the next 4 hours ... I've tryied to seek on mailing lists for specific help but I found only boot-time troubleshooting. What we can't resolve is the hw or sw origin of the problem, scsi terminations seem to be right as like as cable compliancy ... Does anybody can help me ? :((((((((( roberto To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
