I should note that a similar error occurred with the 526 kernel as well, but did not have a chance to copy the panic error msg. I used a digital camera to collect the panic messages today and copied these over to text. The output follows. All services were [OK] except the nifd, for which there is no output status. ...

Version-Release number of selected component (if applicable): kernel-2.6.13-1.1532_FC4 How reproducible: Always Steps to Reproduce: 1. Boot the system with today's kernel Actual Results: Kernel panic as above Expected Results: Successful boot Additional info:
Seeing something very similar with an Inspiron 5160 and 2.6.13-1.1532, happy to provide additional info, tests, etc.
2.6.14-1.1633_FC4smp (from updates-testing) appears to be working fine on my Inspiron 5160 with none of the problems I saw in 2.6.13-xxxx.
Bingo! Indeed, a successful boot with 2.6.14-1.1633_FC4 (non-SMP). Thanks for the heads up Brian!
2.6.14-1.1637_FC4 has been released as an update for FC4. Please retest with this update, as a large amount of code has been changed in this release, which may have fixed your problem. Thank you.
Dave, as per my comment #3 above, this bug was resolved with the .14 testing kernels and continues to be fine with today's stable release. So we can put this one to bed. BTW, on an slightly related note, is there a timeframe for the /proc/i8k fix that we discussed on the FC Test list? This is far from critical and there are of course, workarounds for the time being. Thanks for your time on this!
Dave, my results are the same as Marcs, .14 has been working great and so far no problems with today's 1637 (smp).
ok, will close. Marc, the i8k thing I thought I had fixed already in the current update. I'll double check, and if I've missed anything, I'll drop it into the next update.
