Description of problem: When booting kernel 2.6.18-1.2200.fc5 (upgraded from 2.6.17-1.2187_FC5) : in single user mode (other modes evidently not tested), after a few (5-30) random keystrokes the kernel emits a sound (bell, I guess) and reboots. Version-Release number of selected component (if applicable): kernel-2.6.18-1.2200.fc5 How reproducible: Always Steps to Reproduce: 1. boot in single user 2. use keyboard for a few seconds 3. gasp in awe Actual results: Spontaneous reboot Expected results: No reboot Additional info: - Dell laptop, Inspiron 9300 (WUXGA, nVidia Go 6800) - Removed all external hardware, minimum setup - Made sure kernel not tainted with proprietary nvidia module (renamed before reboot) - Nothing logged to /var/log/messages (when the machine is up long enough to get syslog started)
Created attachment 138681 [details] dmesg output
dmesg looks sane. My first thought is possible hardware problems. Can you try a run of memtest86+ on it ?
Will run memtest86+ first thing in the morning (CET) ; nevertheless, reverting back to 2.6.17-1.2187_FC5 returns to business as usual. (I've got this hunch about blacklisting pcspkr ...)
- A full run of memtest86+ revealed no defects ; - Today, after the memtest run, I was unable to reproduce the erroneous behaviour (though it was perfectly reproducible the day of my report). - The only relevant (?) package update in the interim seems to be kudzu. Sorry for the spam.
