https://bugzilla.kernel.org/show_bug.cgi?id=45151 --- Comment #21 from Feng Tang feng.t...@intel.com 2012-08-21 06:24:41 --- (In reply to comment #16) Here it is the results but something strange happens. I've check three times but I think I'm doing something wrong. The strange behavior is that adding the string of comment #13 (debug log_buf_len=8M cpi.debug_layer=0x1009001F acpi.debug_level=0x082002FF) to kernel boot parameter, You can enter /sys/module/acpi/parameters, check debug_level and debug_layer to see if they are really what we wanted to set. the acpi subsystem work vice versa as booting without the string. This mean that the acpi works with the if statement whereas stop working when is comment out (thus applying the patch of comment #1). On the other hand, when all the kernels are booted without the previous string the acpi subsystem work as described in the bug. Therefore, the string seems to invert the behavior of the acpi subsystem. Yes, that's weird, Comment #1 should work while Comment #9 should not which simply add some debug info. So the too many dmesg output must affect the time sequence of EC(Embedded Controller), the EC on your platform is fragile which force the driver to use polling mode for normal transaction, while normal EC will use driver's interrupt driven mode. Since the dmesg is too many and its ring buffer has been overwritten (the same cmdline set doesn't have so many msg on my platform I can't find any useful info from the dmesg. So need your help to do more tests as follows: 1. add log_buf_len=8M acpi.debug_layer=0x001F acpi.debug_level=0x080002FF to cmdline 2.a test comment #1 + comment #14 2.b test comment #9 + comment #14 2.c test comment #1 2.d test comment #9 hope this time, the dmesg won't be wrapped. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

--- Comment #24 from Feng Tang feng.t...@intel.com 2012-08-21 15:44:57 ---
Yes, that's weird, Comment #1 should work while Comment #9 should not which
simply add some debug info.
There is something that is worse, now in all four test the acpi work
correctly!
I do not understand how the debug string can change this behavior.
I don't think these are worse :) As I said before, this issue is highly bound
with EC driver, with these lots of ACPI debug info, the timing is changed,
which makes your EC driver work normally in interrupt mode, not polling mode
(you can't find GPE storm info any more in these dmesgs).
Could you try the following patch _only_ without any previou patches or those
debug string in cmdline?

https://bugzilla.kernel.org/show_bug.cgi?id=45151 --- Comment #16 from Francesco trent...@dei.unipd.it 2012-08-20 15:09:30 --- Here it is the results but something strange happens. I've check three times but I think I'm doing something wrong. The strange behavior is that adding the string of comment #13 (debug log_buf_len=8M cpi.debug_layer=0x1009001F acpi.debug_level=0x082002FF) to kernel boot parameter, the acpi subsystem work vice versa as booting without the string. This mean that the acpi works with the if statement whereas stop working when is comment out (thus applying the patch of comment #1). On the other hand, when all the kernels are booted without the previous string the acpi subsystem work as described in the bug. Therefore, the string seems to invert the behavior of the acpi subsystem. Hence, I've reset all the kernel source folder and restart to compile all the kernel variant before doing the test. All test are done _WITH the boot string of comment #13 and acpi debug compiling option activated. The dmesg files included are: dmesg_c1.txt: in this case _only patch of comment #1 is applied. In that case acpi_listen doesn't output anything, the acpi subsystem doesn't work. dmesg_c9-new-gpe.txt: in this case _only patch of comment #9 is applied (called new gpe patch). In that case acpi work correctly. dmesg_c14-c1.txt: in this case _both patch of comment #1 and comment #14 are applied. In that case acpi_listen doesn't output anything, the acpi subsystem doesn't work. dmesg_c14-c9.txt: in this case _both patch of comment #9 and comment #14 are applied. In that case acpi work correctly. I hope that this help.

I've done the test as described in comment #4 and with the patch requested in comment #7 and comment #9. The results are: Comment #7 test: in this case I've comment out the three lines of the if statement. The acpi subsystem works and acpi_listen gives the normal output as: video LCD 0087 . The dmesg output are attached in dmesg_comm7.txt file. Comment #9 test: using new gpe patch proposed in this comment doesn't resume the acpi subsystem and acpi_listen doesn't put any output. In any case, the relative dmesg is attached in dmesg_comm9.txt file. I hope that it is the thinks what you want. If more test is needed, there is no problem.

could you post your acpidump binary?

some difference? thanks
