Sankar, does this also happen if you unplug the AC adapter _outside_ of the docking station?
Nope. It has never happened when I remove the AC Adapter. I disconnect from the docking station in office and from the power in home.

So, in an attempt to appear like them, I tried building the kernel and it turned out to be easier (than building my module). I followed: git-clone <linus-tree> su - make defconfig make make modules_install make install And the issue was happening with this upstream kernel that I have built ( 58e20d8d344b0ee083febb18c2b021d2427e56ca ) also. So, it could be an issue in the upstream kernel itself and not specific to ours.

Is there a BIOS update?
No
Have older kernel versions (e.g. 11.0) worked?
Not sure. I have had this laptop only from 11.0 and the problem has been there with 11.0, 11.1 and the kernel I built from sources (as mentioned in comment #16 )
Is there a BIOS option related to AC (e.g. there are some where you can configure battery/performance optimized whether on AC or not). If yes, does switching it help?
I do not find any such.
I doubt that we have such a bug for X60 in 11.0 and still in mainline kernel, the X60 is too widespread, I know several people using such machine at office. Something seem to be fishy. Hmm, ok there are not that much with a docking station...
It is a t60p and not a x60. I tested with few more machines and it was reproducible everywhere.
Does sysreq still work if the machine freezes? Pass the sysrq_always_enabled boot param.
I passed this option. But, sadly, no luck. sysrq did not work when the machine freezes.
Then when it freezes push: SysRq-8 SysRq-T button (SysRq is a key, normally near the top-right corner). You may want to try SysRq while the machine is still running first. Output is normally seen when you switch to console 10: CTRL-ALT-F10.
Output is normally seen when i go to ^-alt-f10 , but when the machine hangs, this output is also hung. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What do you mean by text mode ? (init 3?) I am not sure if anything will get printed at all. I don't have a camera to take a snap shot of it. I will try my best.

With 11.0, I have not observed this often. Because, I was working more from office where there is constant power supply etc. But, with 11.1 , I manually disconnected power supply (to check this bug) and it is hanging whenever i remove the power supply. I tried with around 5-6 t60p laptops here and everyone of them hung (with 11.0 live dvd and 11.1 installation). So, I guess it should be fairly easy to reproduce.

I tried with around 5-6 t60p laptops here and everyone of them hung (with 11.0 live dvd and 11.1 installation). So, I guess it should be fairly easy to reproduce. Please note that I am using a full-featured docking station with pci interface etc. (not a simple port replicator) Hmm all the same models, I expect?
Some ideas: Does it work if you unload the ac driver? Does it work if you unload the thinkpad_acpi driver? Hmm better it doesn't get loaded at all: "blacklist thinkpad_acpi" entry in /etc/modprobe.conf.local should do the trick. Holger, AFAIK the dock event is used to undock disks, how could Sankar try this out explicitly? In normal configuration (without above ideas), try: Copy away previous system logs first: mv /var/log/messages /var/log/messages.bak rcsyslog restart echo 0x21F >/sys/module/acpi/parameters/debug_level tail -f /var/log/message Now let the machine freeze. Hopefully all data could still be saved to disk (you may want to compare the output you see and the output written to disk later), then reboot and last successfully processed ACPI code should pop up in /var/log/messages?

Some interesting observations. Now, the machine hangs if I remove the power supply but if I recconect the power supply again, the machine resumes operations as if nothing happened. Even teh keys that I pressed when the machines was hung, will also get displayed on the screen. (as if they were in a slow queue). I have taken two /var/log/messages files. One is without `echo 0x21F

It could be that your machine exports an extra C-state if on battery. Please try the boot param: processor.max_cstate=2 and idle=nomwait If it works can you double check: cat /proc/acpi/processor/*/power with and without AC. Do you see another C-state popping up there, best paste the output here then. Especially with nomwait, I wonder whether all C-states are entered correctly, even if on battery.

I hope you can still access the machine? Thanks to your debug output from comment #29, one can see that: - GPE 27 is triggered (probably the AC General Purpose Event) and the ACPI function _Q27 is executed. - There the function UMCS with a value of 12 is invoked which triggers a System Management Interrupt (function is called SMI) and the machine enters SMM (System Management Mode) and executes BIOS code. This happens behind the OS back. - The next function invoked is a simple Sleep, which is probably to wait for the BIOS code to finish execution Now it hangs. So I very much expect: - there is a bug in the BIOS code, plus: - We might do something different (HW setup? ACPI?) compared to Windows which triggers this bug. It might be that this also happens (on specific conditions?) on Windows. Sankar (and only Sankar as this code fits his BIOS, everyone else who wants to do this test has to upload acpidump of his machine), can you please follow the steps I describe with the attachment upload and try out whether this workarounds the bug and everything is fine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This might lead to other side effects when (un-)plugging the AC, so best only do it to verify the bug fixed or not. If it works now we need input from Lenovo, they seem to have a bug in their BIOS SMM code then. (Maybe an endless loop polling for AC state or something?

Can you double check whether the DSDT really was overridden: dmesg |less then look out for something with initrd overridden by host OS or similar.
Yes I could see the message "ACPI: Table DSDT replaced by host OS" But without acpi_no_auto_ssdt there was a warning "ACPI: DSDT override uses original SSDTs unless "acpi_no_auto_ssdt"" So I tried both with and without that parameter. But not much of difference in behavior.

Yes, the system recovered after powering up again! And I was able to get the dmesg.

You said you are running the latest BIOS, but not the exact version, could you still add that info. dmidecode can tell you.
I was running "79ETD8WW (2.18) " but just now updated to " 79ETE3WW (2.23)". But it didn't help. :( Another colleague with very old bios version "79ET65WW (1.09a) 27/7/2006" do not have this problem !! So it could be a bug introduced after that version! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Then you could claim them as defective.

But isn't it still a bug? Lenovo may not want to fix, as it is for legacy devices, but I am writing a mail to them. At least they should document it as a known issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
