Re: Fan speeds on HP nc6400 and nc8430
I managed to get a HP NX 6330 laptop to test HP laptop related issues discussed here. But the bug http://bugzilla.kernel.org/show_bug.cgi?id=7813 seems to be NOT reproducible on my NX6330. This fact prompt if there are any essential difference between NX6330 and NC6400. The BIOS of my NX6330 even declares itself is NC6330.

Take a look at this: http://daniel.graziotin.net/2006/12/02/hp-nx6325-and-friends-thermal-problems-solved this fixed my thermal problem. And make sure you unload the psmouse module during halt/reboot otherwise you have problemes when you start your notebook again. (symptom's: very long BIOS-Boot, ACPI-problems (thermal)..) I have a patch that should fix the psmouse unload thing (at the end). Not sure whether it's still needed in 2.6.20-rcX, there was some work done... it definitely helps on 2.6.18 and 2.6.16 kernels. Ok, I quickly tried on 2.6.20-rc7 and it seems to work without the patch. Maybe Dmitry can comment on that and push this one if still needed? It's quite difficult to get the overview over the HP problems, as there are several, some quite weird, and a lot different reports. I've found out that the psmouse thing really fixes things. and I got a lot reports that Alexeys patch (and the unregister_serio_drivers attached) fixes up things: https://bugzilla.novell.com/show_bug.cgi?id=179702 https://bugzilla.novell.com/show_bug.cgi?id=234475 As this patch broke Linus' machine, I understand that Len is a bit anxious, but a lot people tested the reworked patch (it's currently in 10.2 and SLE10-SP1 SuSE branches), it would be great if Len can push it at least for the next kernel cycle... What is still broken, but patches are available, is fan state after suspend/resume. Thanks to Rafael, there is a list of patches that seem to help (including Alexey's and some others) here: http://www.sisk.pl/kernel/patches/2.6.20-rc5/ Most of them seem to come from: http://bugzilla.kernel.org/show_bug.cgi?id=5534 and http://bugzilla.kernel.org/show_bug.cgi?id=7122 Can someone give an overview about what is already submitted, what is going to be merged and where/when (-mm, rcX, 2.6.21-rc1, ...).

Thanks, Thomas --- Subject: Unregister serio drivers on shutdown From: Thomas Renninger [EMAIL PROTECTED] Unproved theory: It seems that the Embedded Controller needs this at ACPI shutdown time: psmouse_set_state(psmouse, PSMOUSE_CMD_MODE); psmouse_set_state(psmouse, PSMOUSE_IGNORE); done in psmouse_disconnect in psmouse module. If this is not done on shutdown it leads to very strange BIOS/EC behaviour on latest HP laptops which even survives a reboot (cpufreq cannot reach max freq, BIOS takes long to boot, etc.). Then the fixed kernel needs to be booted twice, that machine reaches max freq and behaves normal again.

RE: Thermal resume regression
Hi, Could you try the patch from http://bugzilla.kernel.org/show_bug.cgi?id=7887 to see if it's related? Regards. Konstantin. -Original Message- From: [EMAIL PROTECTED] [mailto:linux-acpi- [EMAIL PROTECTED] On Behalf Of Markus Demleitner Sent: Monday, February 05, 2007 6:36 PM To: linux-acpi@vger.kernel.org Subject: Thermal resume regression Hi, Since 2.6.20 is out and nobody else seem to complain, I thought it's time to ask -- From kernel version 2.6.18 on my JVC XP731 (a centrino-based subnotebook) would freeze when resuming from echo -n mem /sys/power/state where it woke up flawlessly before. Turns out it did this because in drivers/acpi/thermal.c, function acpi_thermal_resume, a call to acpi_thermal_check was introduced (that's line 1415 in 2.6.20). The lockup at resume time is deterministic, i.e., it is independent of the actual temperature of the device(s). Commenting it out results in a flawless wakeup (as does removing the thermal module at suspend time). Now, I have to admit I didn't investigate matters much further, but still: acpi_thermal_check does quite a few rather fancy things, and regardless if the freeze on resume is an issue of the JVC (as the lack of other complaints suggests) or not -- is it absolutely necessary to run it during resume, when things are a nightmare to debug (which is one reason I didn't investigate further)? I for one would appreciate if it were only called after the system is up and running, when one could at least see what the kernel thinks it's doing... Disclaimer: I only have very shady ideas what's actually going on with ACPI thermal management. If not calling acpi_thermal_check actually significantly increases the likelihood of fried machines, disregard all this as layman babble, and I'll just add thermal to the list of modules that don't survive a suspend to RAM.

[PATCH 1/2] ACPI: ibm-acpi: add Ultrabay support for the T60p ThinkPad
From: Theodore Ts'o [EMAIL PROTECTED] The following patch adds support for obtaining the status and ejecting Ultrabay devices for the T60p Thinkpad; my guess is that it probably works on T60 Thinkpads and probably more recent Lenovo latops as well. With the 2.03 BIOS I have been able to eject a SATA drive in an Ultrabay carrier by using the command: echo 1 /sys/class/scsi_device/1:0:0:0/device/delete and upon re-inserting the it back into the device and issuing the command: echo 0 0 0 /sys/class/scsi_host/host1/scan have the device appear again. (With the 1.02 BIOS the device does not function when re-inserted, even after a warm boot; a cold reboot is required to store the Ultrabay device's functionality.) More complicated Ultrabay eject and insert scripts can be found on the ThinkWiki, although it's important to comment out the hdparm -Y as it apparently doesn't work or do anything, and causes the eject process to hang for about a minute.

Re: ACPI bytecode hardware registers access
Is your ioport included in the microsoft's list being blocked by XP? Please give me an example (acpidump output from a real box) that demonstrates ACPI is missing something which must be done through native driver. I'm wondering the designer of the box should already known AML code will directly access these ioport. why they needs some other native driver to access same set of ioport at same time with acpi. It sounds like obvious broken design. So my real question is the native driver is really wanted by the platform designer? As a hacker, it make senses to discover more hardware/platform features. But do these features make sense to the designer of the box. On 2/5/07, Rudolf Marek [EMAIL PROTECTED] wrote: Hello, To all: Please continue CCing me and the lm-sensors list thanks. Luming Yu wrote: Yes, that is bad to simultaneously access same hardware by ACPI and native drivers without coordination. But the problem is if nativer driver is really needed with the existence of the ACPI support for that device? Yes for example, BIOS will export though ACPI just one temperature _TMP but the chip monitors voltages and more temps etc etc. So from the lm-sensors point of view the answer is yes we need a full driver for hardware monitoring. Do you know the features that are NOT supported by ACPI? Yes as I wrote above - the voltages, fan speeds, various types of alarms... Instead of one temperature reading, I got 9 voltage readings, 3 temps, 5 fans etc etc Probably, just writing a acpi driver for SMBus controler could solve this problem completely. Just my intuition. Please correct me if I'm wrong. Problem is that the device manufacturers may do what they want in ACPI bytecode. We cannot expect them to implement smbus bus control as specified in the specs. They just drive the registers on their own. What I'm trying to implement is the ACPI isolation from selected hardware somehow, because the ACPI bytecode can contain code that modifies virtually any hardware in the system without the clue what others drivers do.
