Summary: Kernel freezes during boot when AC is unplugged Product: ACPI Version: 2.5 KernelVersion: 2.6.25-rc8 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Power-Processor AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Latest working kernel version:2.6.24.4 Earliest failing kernel version: 2.6.25-rc1 Distribution: Gentoo Hardware Environment: NB Asus A6JC 2x Genuine Intel(R) CPU T2300 @ 1.66GHz Software Environment: gcc 4.2.3 Problem Description: Kernel freezes during boot if AC is unplugged. I doesn't freeze every time but very often. It freezes after this two lines: Apr 2 00:46:15 kedgecomp ata1: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0xffa0 irq 14 Apr 2 00:46:15 kedgecomp ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xffa8 irq 15 If I boot with debug parameter then it prints one more line and then freezes. Apr 2 00:46:15 kedgecomp Switched to high resolution mode on CPU 1 If kernel is compiled without CONFIG_CPU_IDLE then it boots. I've also tried to revert http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9a0b841586c3c6c846effdbe75885c2ebc0031b0 or boot with processor.max_cstate=1 as Venkatesh Pallipadi suggested in bug 10093, but it didn't help Also if it doesn't freeze during boot with unplugged AC then it often freezes when Gentoo prints "Setting system clock using the hardware clock UTC" the clock script uses "/sbin/hwclock" Any suggestions how to fix it?
