<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Thanks a lot for your contribution ! <p>well now that you mention it, if i remember well, it seems that i started getting this behaviour after installing the aha2940 .... <br>but the freeze also happens when the SCSI is not sollicited since the only device plugged on the SCSI is the JAZ and i don't use it that much. <br>Last hang i had on 2.2.10 was when i was accessing the JAZ ... ( creating a big tar.gz on it ) but i also had it without playing with SCSI. <br>If most of the people experiencing this behaviour have this card then we might have a clue .... <br> <br> <br> <p>Ward Vandewege wrote: <blockquote TYPE=CITE>At 22:49 15/06/99 +0000, Charles-Edouard Ruault wrote: <br>> <br>> It's an AMD K6-2 400 on an epox motherboard, 128MB RAM , IBM IDE HDD , <br>> AHA 2940 SCSCI card on which i've plugged a IOMEGA JAZ and an intel <br>> ehterexpress pro 100 NIC card. <br>> <br>> since the beginnig ( kernel 2.2.x ) i've been experiencing a lot of <br>> random system hangs ( no messages on the console or in the log files ). <br>> The only way after such a hang is to do a hard reset. <p>Same thing here. My hardware is the following: PII-350, 128MB RAM, Dual IDE <br>Samsung 6.4GB HDD, AHA 2940 SCSI card (only used for my cdroms, scanner, <br>SyJet), ISA ne2000 clone and PCI ne2000 clone. <br>As you can see the only thing that matches with Charles-Edouard's setup is the <br>AHA 2940 SCSI card. Am I dreaming or was there an AHA2940 in every machine <br>mentioned on this list that has this behaviour? <p>The Linux box is a smb fileserver also acting as gateway/firewall for an <br>internet connection, masquerading the internal network. <p>I can reproduce the hangs, that seem to occur when there is a lot of <br>network/disk traffic. When machines behind the firewall use a windows file <br>synchronization utility, comparing files between the Samba share on the Linux <br>server and the local disk, the Linux server freezes after a 20-30 seconds. No <br>messages anywhere, nothing in the logs, alt-sysrq doesn't do anything anymore. <p>It has happened too when someone started ftp-ing a big file (10+MB) at high <br>speed (100+ Kb) through the firewall, or even at random, mostly in X sessions <br>on the firewall. <p>I have seen this behaviour with stock 2.2.7, 2.2.9 and 2.2.10. I have tried <br>reproducing it with 2.2.5-22 (the latest RedHat 6.0 kernel update), but could <br>NOT. That kernel seems to behave properly. <p>Hope this helps - if you need more info please let me know. <p>Ward.</blockquote>
