Hi, while trying to debug a hibernation/rtc_cmos alarm wakeup problem in 2.6.22 (or later) I noticed that the latest kernel crashes (or gets stuck sometimes) during boot after the message: SMP alternatives: switching to UP code Every kernel up to 2.6.22.1 works fine on the system. I've attached the log file taken from the serial console (4 boot attempts with different acpi= options) and the .config of the kernel. The kernel is from the Fedora 8 development line. BTW: While this is a Fedora 8 kernel I had the same problem with a plain 2.6.23-rc3 kernel with the latest suspend/hibernate patches applied. Is there any more information I should collect and attach in further postings? Please include my e-mail address in the CC as I'm not subscribing to this list.
