Summary: select gives erronous replies for /proc/acpi/battery
Product: ACPI
Version: 2.5
Kernel Version: 2.6.30
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: acpi_power-batt...@kernel-bugs.osdl.org
ReportedBy: sve...@gmail.com
CC: sve...@gmail.com
Regression: No
Starting in 2.6.30, using select() on any file under /proc/acpi/battery gives
the wrong reply, in that it suggests they should be readable immediately but a
read() call in fact blocks for 4-5 seconds.
Prior to this, select worked correctly in that read in fact always returned
immediately.
This is on a MacBookPro4,1, as far as read-edid is concerned. I'll happily help
with any further information you might find useful, although since I'm using
this machine for work I can't take it offline to run a git-bisection.
