Occasionally on a warm boot, one or more CPU's do not respond. This always occurs after the following message appears after 'shutdown -r':
Jul 30 16:18:58 musrum kernel: rpciod: active tasks at shutdown?!
There are no warnings or errors other than this in any of the log files. A message is displayed on the console, which unfortunately I don't have, but it is something about entering the power down state. This is the last message displayed, and the machine never powers down. A warm reset will now always cause one or more CPU's to fail with the following messages, (or ones like it) in /var/syslog.
Jul 30 16:19:48 musrum kernel: CPU #1 not responding - cannot use it. Jul 30 16:19:48 musrum kernel: Booting processor 1/2 eip 2000
There is also a noticable (about 1 sec.) pause after the 'Booting processor' message above; this pause normally does not occur. The only way to recover from this problem is a cold restart. A longer excerpt of the syslog is at the end of this email. The boot process proceeds normally, and the system comes up. The only noticable symptom in this state is that there are only 3 CPUs (sometimes only 2). Of course, that's a Good Thing!
Kernel 2.6.0-test1-G2, Based on Slackware 9.0, with upgrades for 2.5.x operations. HT enabled. I have seen this on occasion since 2.5.67 which was the earliest 2.5.x I ran extensively on this machine.
If there is anything I can do/provide, please let me know.
