I have been encountering some intermittent lockups while running recent 2.6.22.3-*-default kernels on a HP dv6400 laptop (Turion64 X2 TL-56 processor) These kernels where sync'd out on factory some time after Friday (17 Aug) (I recall a 2.6.22.3-2 and currently the kernel-default-2.6.22.3-5) I did not have this problem with the previous -default kernels from Factory. I am now running a kernel-vanilla-2.6.22.3-20070818105014 (from /pub/projects/kotd/HEAD) without encountering any lockups. # rpm -q kernel-vanilla --changelog | head -3 * Sat Aug 18 2007 - trenn@suse.de - patches.arch/acpi_autoloading_ia64_hp_fix.patch: Use acpi_device_id for IA64 HP driver, otherwise those fail to boot. I have tried "nmi_watchdog=2 crashkernel=..." to try get a dump that will shed some light on the issue but no luck. I have noticed some boot issues stemming from boot.clock so added a file /etc/modprobe.d/rtc which contains: blacklist rtc_cmos blacklist rtc_core blacklist rtc_lib Even with the above blacklisted, the system still has intermittent lockups with the -default kernel, some times shortly after I get logged in. Other times it will take over an hour before a lockup occurs. Any tips or suggestions? # rpm -q kernel-default-2.6.22.3-5 --changelog | head -3 * Fri Aug 17 2007 - teheo@suse.de - patches.drivers/scsi-throttle-SG_DXFER_TO_FROM_DEV-warning-better: SCSI: throttle SG_DXFER_TO_FROM_DEV warning message better # rpm -q kernel-vanilla-2.6.22.3-20070818105014 --changelog | head -7 * Sat Aug 18 2007 - trenn@suse.de - patches.arch/acpi_autoloading_ia64_hp_fix.patch: Use acpi_device_id for IA64 HP driver, otherwise those fail to boot. * Fri Aug 17 2007 - teheo@suse.de - patches.drivers/scsi-throttle-SG_DXFER_TO_FROM_DEV-warning-better: SCSI: throttle SG_DXFER_TO_FROM_DEV warning message better -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
