From: "Jonathan Gilpin" To: "David Malone" , Cc: , , "Don Bowman" Subject: Re: kern/59719 Re: 4.9 Stable Crashes on SuperMicro with SMP Date: Sat, 29 Nov 2003 01:22:21 -0000 I've run memtest (memtest86.com) kindly provided by Don and it passed all the tests. I've installed installed a kernel module to test for memory errors and found that again no memory errors are found... So this means it's either a problem with the CPU's or a geniune bug in the kernel. (bugger!) I'm going to switch the CPU's around (we dont have any spare) and then try and get spares from my supplier to test with. Today I aslo enabled Hypterthreading in the BIOS and Disabled MPS 1.4. This had no effect and the box continued to crash... The strange thing is that this box ran fine using Suse... The box BTW is a SuperMicro 6013-I (some of you have asked). Is it worth enabling any debug stuff in the kernel? I'm not familair with gdb but can follow instructions to provide more info to anyone investigating possible bugs such as these... Unless the switching of the CPU's around works I'm going to have to go back to 1 CPU for stability...
