Description Jiri Slaby 2005-09-27 10:12:28 UTC

Most recent kernel where this bug did not occur:
2.6.11.x
Problem Description:
2.6.11 and older kernel worked fine, battery status was OK. Now, in latest
kernels, there are bad data in /proc/acpi/battery/BAT0/ and it oscilates -- I
have 320 hours remaining, 65 hours, 14, 320, 65 and so on in my window
manager... (the remaining capacity is variable in `state' file).

I will attach diff between state and info in both kernels (2.6.11.7 and 2.6.13)

I use ec_burst in latest kernels, because without it, acpi is not working.

Please describe laptop model. 
 
Please try linux-2.6.14-rc1 with ec_burst=1. 
try last patch at bug 4980 and boot with ec_burst=1. 
If it doesn't work, please boot kernel with acpi debug option enabled, and 
post dmesg, as well as acpidump output. 
 
Thanks
