On an HP DL385 first-generation system, 10.0 BETA3 and 9.2-RELEASE most of the time fail to boot, freezing the system after the following lines, requiring a cold boot: Timecounter "ACPI-fast" frequency 3579545 Hz quality 900 acpi_timer0: <32-bit timer at 3.579545MHz> port 0x908-0x90b on acpi0 pcib0: <ACPI Host-PCI bridge> on acpi0 pci0: <ACPI PCI bus> on pcib0 The next lines would have been, if reached: pcib1: <ACPI PCI-PCI bridge> at device 3.0 on pci0 pci1: <ACPI PCI bus> on pcib1 This behavior was never seen before 9.2. It happens with the 10.0BETA3 install disc, also, though not with the 9.2-R install disc. No similar problems have been noticed on these systems with any level of 9.1-R or before. When the Verbose boot option is "on", the system always completes the boot sequence in 9.2 and 10.0. These items stand out from the verbose dmesg.boot from 10.0B3 disc1: WARNING: This architecture revision has known SMP hardware bugs which may cause random instability ACPI BIOS Warning (bug): Invalid length for FADT/Pm1aControlBlock: 32, using default 16 (20130823/tbfadt-682) This similar message appears in an always-working 9-1-R boot of the same system: ACPI Warning: Invalid length for Pm1aControlBlock: 32, using default 16 (20110527/tbfadt-638) We have quite a number of these DL385 gen1 systems, and they have, in practice, been very stable. Are they going to be unstable under 10.0? Is there a workaround? Let me know what other information to supply. stu
