------- Comment #20 from [EMAIL PROTECTED] 2008-06-26 14:34 ------- ok, works ... till somthing happens. Tested twice, pattern seems clear: logger -t acpi.debug -p kern.info ===ACPI DEBUG START=== while true;do cat /proc/acpi/battery/BAT0/* &>/dev/null & sleep 2; ps $! && break echo -n . done logger -t acpi.debug -p kern.info ===ACPI DEBUG END=== without hald, it goes on for hours, but during night only: # grep === /var/log/socklog/main/current user.info: Jun 26 01:20:01 acpi.debug: ===ACPI DEBUG START=== user.info: Jun 26 08:39:44 acpi.debug: ===ACPI DEBUG END=== that's typically the time the user starts his's wmaker session, then a wmapp starts to poll acpi: # cat mutex_no-hald.log ACPI Interpreter Mutex acquired by: wmacpi, use count: 220414 and in dmesg: DEBUG: acpi_dump_stack ---------------------- Pid: 12015, comm: wmacpi [<c0262a2e>] ? acpi_dump_mutex+0x0/0x95 [<c01b8f19>] proc_file_read+0x1c9/0x280 [<c01b8d50>] ? proc_file_read+0x0/0x280 [<c01b411c>] proc_reg_read+0x6c/0xc0 [<c0180084>] vfs_read+0x94/0x130 [<c01b40b0>] ? proc_reg_read+0x0/0xc0 [<c01804bd>] sys_read+0x3d/0x70 [<c0103fee>] sysenter_past_esp+0x5f/0x85 ======================= and from then on my process if locked solid: 12020 pts/1 D 0:00 cat /proc/acpi/battery/BAT0/alarm ... that's 2.6.25.6. Likely, without hald, during that test time acpi is read by my 'cat' only, since the nb is on ac and nothing bothers to poll the battery level, nor the ac state, since all is expectd to react on a acpid event. But wmacpi polls ac/battery 3 times/min, clashes with 'cat' and one or the other gets stuck there. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
