Hi, I noticed some MCE dumps getting mailed to the list in September. From Alan Cox's comments I gathered that he was looking for similar dumps [at least then]. My workstation produced one yesterday and I hope this is still relevant info. This machine has seen some moderate to heavy use for a few months now and this is the first time this [MCE] has happened. We have, however, experienced two spontaneous and unexplained reboots. I am not subscribed to the list, so send me a personal mail if you require more information [ I'll check the list regularly though ]. The kernel is an out-of-the-box 2.2.17. I also note that the other people normally include register dumps. Mine didn't produce any of that, just the MCE line. Thanks, gerhard Here are the details: -- from /var/log/messages [and also sprayed all over the terms] Dec 4 13:33:15 pamela kernel: CPU 0: Machine Check Exception: 0000000400000000<0>Bank 4: b200000000040151general protection fault: 0000 Dec 4 13:33:15 pamela kernel: CPU: 0 -- /var/log/dmesg Linux version 2.2.17 ([EMAIL PROTECTED]) (gcc version 2.95.2 19991024 (release)) #4 SMP Fri Nov 3 17:47:06 SAST 2000 Intel MultiProcessor Specification v1.1 Virtual Wire compatibility mode.
