Is your OS installed either sda or sdb? Because I get this type of message using a single disk... On which my FC5 stands... I'll give it a try tonight and see if I can cause the problem manually but I doubt I'll be able to stop the system from hanging... Unless my bug is not related. - vin -----Message d'origine----- De : Roger Heflin [mailto:rheflin@xxxxxxxxx] Envoyé : 26 avril 2006 10:42 À : Fortier,Vincent [Montreal] Cc : Linux-Kernel; linux-ide@xxxxxxxxxxxxxxx Objet : Re: Issues with sata_nv and 2 disks under 2.6.16 and 2.6.17-rc2 Fortier,Vincent [Montreal] wrote: > I think I might be having the "same type of bug" or something related using sata_via? > Bug opened at bugzilla: > http://bugzilla.kernel.org/show_bug.cgi?id=6317 > > This started appearing with 2.6.16. It often does it using only one SATA HD. It does not do it at every boot but often starts doing it after a little while (a few hours...) and finally hanging my PC. > > - vin > > I can duplicate my problem everything, and I can make it stop a will. doing "dd if=/dev/sda of=/dev/null bs=64k &" and then "dd if=/dev/sdb of=/dev/null bs=64k &" will cause the problem within a couple of seconds. Doing "kill %1 %2" (assuming the dd's are %1 and %2) will stop the machine from hanging on disk io within 30-60 seconds. Once it hangs it does not appear to do any disk io until the offending processes are killed.
