I am running rhel2.1 and rhel4 on some Compaq 8 way machines. Mine are 740's and the only thing I really found to be necessary was to run on the bigmem kernel since my machines had more 32gigs of memory in them. Other than that I have not had to pass any special kernel arguments to get the machines to run stable. In fact until a recent hardware issue, my 2.1 server had nearly 3 years of uptime. darren -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of jOe Sent: Tuesday, May 16, 2006 3:40 PM To: redhat-list@xxxxxxxxxx Subject: Re: RHEL3 U5's kernel is unstable for 8-way SMP server? I've searched the redhat's bugzilla and googled again,maybe add nomce or mce=off into boot parameter list will solve the problem? because the system is in production, anyone ever use this way on 8way system?
