Hello,

I tried 2.6.21 and still had the same problem, I was going to back
farther but then I decided to try a few things with my 2.6.23 config.

$ diff config-2.6.23 newconfig-2.6.23-gentoo
140,151d139
< CONFIG_CPU_FREQ=y
< CONFIG_CPU_FREQ_TABLE=y
< CONFIG_CPU_FREQ_DEBUG=y
< CONFIG_CPU_FREQ_STAT=y
< CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
< CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
< CONFIG_CPU_FREQ_GOV_USERSPACE=y
< CONFIG_CPU_FREQ_GOV_ONDEMAND=y
< CONFIG_X86_ACPI_CPUFREQ=y
< CONFIG_X86_P4_CLOCKMOD=y
< CONFIG_X86_ACPI_CPUFREQ_PROC_INTF=y
< CONFIG_X86_SPEEDSTEP_LIB=y
456a445,446
> CONFIG_SQUASHFS=m
> CONFIG_SQUASHFS_FRAGMENT_CACHE_SIZE=3
488,490d477
< CONFIG_DEBUG_KERNEL=y
< CONFIG_DETECT_SOFTLOCKUP=y
< CONFIG_SCHED_DEBUG=y
492d478
< CONFIG_FORCED_INLINING=y

config-2.6.23 is the vanilla kernel's config that was experiencing the
hangs.  2.6.23-gentoo was also experiencing the hangs.  Then, I
disabled CPU frequency scaling (and a few other things I guess,
looking at the diff..) and recompiled and..  no hangs yet.  Uptime 3
and a half days.

If you wish I can use a vanilla kernel.
