Machine hangs after some time even if kept idle. system clock seems to stop. Steps to Reproduce: 1. start kernel-smp-2.6.8-1.521 on IBM ThinkCentre M50 desktop PC with Intel Pentium 4 with hyperthreading: vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 9 cpu MHz : 2993.605 cache size : 512 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflu sh dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 5914.62 Start KDE or gnome or XFCE desktop. 2. Machine hangs after 5 to 8 hours, even if kept idle with or without screensaver. 3. Needs a hard reboot (disconnect power, switch on). Actual results: Hung machine. Expected results: Hung machine. Hard reboot needed. Additional info:
kernel 2.6.6-1.435.2.3smp works fine
Same for me. Hangs totaly, unable to unblank sreen, nothing in logs. Same kernel, with a hyperthreaded Xeon in a Dell PowerEdge 1750.

mass update for old bugs: Is this still a problem with the 2.6.9 based update kernel ?
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
