          Platform: All

Most recent kernel where this bug did not occur:2.6.22
Distribution: Ubuntu 64bit 7.4 or Gentoo
Hardware Environment: HP Pavilion dv9398eu, chipset: nvidia MCP51 proc:
AMDTurion64x2, bios: F.38
Software Environment: Ubuntu 7.0
Problem Description:
Computer freezes almost every time I (or boot scripts) run hwclock. Problem
disappears with i386-kernel or if noapic or acpi=off kernel option is used.
hwclock works if almost no modules are loaded. noapic or acpi=off introduces
other problems, such as usb not working. If rtc is disabled in kernel then
hwclock doesn't freeze computer, but no time is reported.

Steps to reproduce: run hwclock
