Sounds like the problem I have - with a single on-board fxp0 and sym scsi- controller (SMP only) Problem went away after enabling extended IO-APIC on mobo which resultet in different IRQs being assigned to fxp0, sym0 and sym1. Presumably due to different IRQ-Handling of ncr, no system hangs with ncr instead of sym. (Without extended IP-APIC, fxp0, sym0 and sym1 are assigned to the same IRQ). According to Gérard Roudier this could be an IRQ stall (in my case at least). Presumably similar problems (other users): - System hangs (sym) with heavy disk io - System hangs with heavy network io I'm still waiting for him to finish some testing patches/routines so I can go and analyze the IRQ behaviour on my system (I'm not in IRQ programming...). -- Holger Kipp, Dipl.-Math., Systemadministrator | alogis AG Fon: +49 (0)30 / 43 65 8 - 114 | Berliner Strasse 26 Fax: +49 (0)30 / 43 65 8 - 214 | D-13507 Berlin Tegel email: holger.kipp@alogis.com | http://www.alogis.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
