Because the system stayed up for a bit, when I rebooted, I discovered the following in /var/log/messages:

My naive reading of the above is that the system thinks the hard drive "froze", it then tried to "soft reset" which appeared to work, at least for a bit.......
Can someone elucidate further (please!).
Still seeing this with a more recent kernel, Tom? This looks like the same as #479476. cheers, Kyle *** Bug 479476 has been marked as a duplicate of this bug. *** Nope. I haven't seen this since the above report. My logs go back to 25 January. Close? I'll wait to see what Zaitcev says. I suspect it was just pre-rc1 merge teething pains though. cheers, Kyle |
Created attachment 328222 [details] picture of screen with BUG message Description of problem: I've been getting "random" freezes running kernel-2.6.29-0.9.rc0.git4.fc11.x86_64. Most of the time, I get nothing in the logs, but I just got one that spewed the following on my console windows just before completely freezing: kernel:BUG: spinlock lockup on CPU#0, pulseaudio/3263, ffff88005911e010 (Tainted: G W) Hard rebooting (power cycle/etc.) again shows nothing in /var/log/messages. System is Thinkpad X61. Typically, when the freeze occurs, I get the "repeat .25 seconds of sound clip" repeating constantly. I attach a picture of the above message. Version-Release number of selected component (if applicable): kernel-2.6.29-0.9.rc0.git4.fc11.x86_64 How reproducible: Repeatable, but random Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
