Is this problem specific to 2.6.13-rc6-mm1, or does 2.6.13-rc6 also exhibit the bug? Yes. 2.6.13-rc6 also exhibit the bug. Before suspend cat /proc/acpi/battery/BAT0/info show: ======================out_1============================== present: yes design capacity: 3800 mAh last full capacity: 3248 mAh battery technology: rechargeable design voltage: 7400 mV design capacity warning: 330 mAh design capacity low: 99 mAh capacity granularity 1: 16 mAh capacity granularity 2: 16 mAh model number: serial number: battery type: LION OEM info: Samsung ============================================================ after resume first second: =====================out_2================================= present: yes design capacity: 972800 mAh last full capacity: 831488 mAh battery technology: unknown design voltage: 1894400 mV design capacity warning: 84480 mAh design capacity low: 25344 mAh capacity granularity 1: 4096 mAh capacity granularity 2: 4096 mAh model number: serial number: battery type: LION OEM info: Samsung ============================================================= after 5 seconds =====================out_3=========================== present: no ====================================================== if battery module unloaded bevore sleep and loadad after resume it's show example =out_2= without eny changes, power and sleep buttons not working. It's looks like EC hang up :) if battery module unloaded after resume and loadad agen it's show =out_1= and all working properly. Please try latest ec patch at bug 3851. And boot with ec_burst=1 and ec_burst=0 This pathc i tested for about one week and reportet what i cant put laptop to suspend mode. With both command line arguments. Is this a regression vs. a previous release which would suspend/resume to RAM and then show correct battery info, or has this failed for all tested releases on this box? It was bug 4535 with kernel 2.6.12-rc3 & 2.6.11.7 batt_info: ========================================================= present: yes design capacity: -656877352 mAh last full capacity: -825307648 mAh battery technology: unknown design voltage: -387389208 mV design capacity warning: 1246382666 mAh design capacity low: 1667457891 mAh capacity granularity 1: 269488144 mAh capacity granularity 2: 269488144 mAh model number: serial number: battery type: LION OEM info: Samsung ========================================================= and with 2.6.13-rc1-mm1 worked properly. It was nofing with resume ore something other, jast worked :) Now it show correct batt.info before sleep. > Is this a regression vs Maybe. Bug 4534 was RESOLOVED with 2.6.13-rc1-mm1 too. > or has this failed for all tested releases on this box? No. Kernel 2.6.13-rc1-mm1. But this bug is a bit different. kernel 2.6.13-rc7: it's looks like you changed default ec_burst to 0. Result,after boot it's show "batt no", "ac_adapter off" - realy streng. Same result i get with 2.6.13-rc6-mm1 ec_burst=0. But 2.6.13-rc7 ec_burst=1 show correct info after boot and after resume. |
