--------------6D16C2A0A58500631E847A76 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Further to my earlier posting with the stupid subject of FAQs. Here's more info: Have attached files in /proc/scsi/aic7xxx/* (Sorry if atttachments are pain but don't know how to import files into Netscape) System 2940 currently only running a tape, 3940 with 4Gb Quantum on Channel A & 9Gb QuantumViking II on B. Full symptoms - System seems OK until second drive used extensively (eg mkfs) and then hangs with no visible messages and drive ligh on on second drive. Have tried kernel 2.2.5 with aic v5.1.5 but they all seem to do the same. TCQ is off by default - Turning on makes things worse, hangs during boot phase. All was fine with SuSE 5.2, but I need to upgrade now because of libc6 apps. Many thanks for prompt suggestions so far Nick --- Eric NOULARD wrote: > > From owner-aic7xxx@FreeBSD.ORG Wed Jun 16 09:54:58 1999 > > Delivered-To: aic7xxx@freebsd.org > > From: Nick Taylor <nt@dataskill.co.uk> > > Hi > > > > Are there any FAQs or digests available for this list?
