Issues with 2.4.20/2.4.21-rc1[-ac3] and 2.5.68 on a Dell laptop

Hi; FWIW, I've got an Inspiron 4000 running 2.5.68. Neither /proc/sys/cpu/0/speed nor /proc/cpufreq all me to change any values (speed has min==max==0, cat cpufreq lists no parameters). cat i8k works, causing no such lock. I don't use suspend/resume. The screen brightness buttons work and do not hang. ACPI kind of works; cat BAT0/info causes "Error: ul_allocate: Attempt to allocate zero bytes". The same occurs when I reinsert the battery.

PS: I can confirm that /proc/acpi/button/lid/LID/state works; I just sshed in to check.

Hi Alan,
first of all, thanks for you -acX, it solved several issues in my Dell
X200, the inclusion of XFS is great, and dri/drm with xfree 4.3 works perfectly with the i830M (thanks).But there still several problems (with APM enabled, no framebuffer):
- With cpufreq enabled, the kernel hangs if you change the CPU speed _after_ a suspend/resume via the old interface (
/proc/sys/cpu/0/speed, (also repeatable in a vanilla or -rc1 kernel)). It doesn't happen if my governor program uses/proc/cpufreqinstead. I saw this bug also with the original cpufreq patch and also with 2.5.68.- cat
/proc/i8kproduces a long kernel lock, everything gets locked for a few seconds. If you are playing a music, you must restart the program in order the get alsa sync'd again.- After suspend/resume, the kernel hangs during a shutdown (just like the infamous w98se shutdown bug :-), it happens after all processes have been TERMed. Sometimes the screen goes white (it happens also with Marcelo tree). I tried this with almost every different version and bios workaround in APM kernel options. I also happens with 2.5.68.
- The kernel hangs/lock hard if IO-APIC is enabled and you try to change the screen brightness (<Fn><[UP][DOWN]-Arrow>). It also happens with 2.5.68.
- ACPI doesn't see the battery, the shutdown buttons just turn down with notifying the kernel, suspend doesn't work. Also seen with ACPI original patches and 2.5.68.
- Only happens with -ac3 version: the poweroff button turns the machine off inmediately, it doesn't wait for a few seconds, as previous versions.
Regards,
