------- Additional Comments From [EMAIL PROTECTED] 2006-05-18 15:39 ------- OK I upgraded the bios and made sure that everthing that looked like two processors should be enabled was. Booting 2.6.12 from knoppix (with no extra flags other than debug) works; i.e., I see both processors. Booting 2.6.16.16 hangs unless I put acpi=off, where I don't see the second processor. I tried simply booting with noapic and debug, but that hangs too. The last line on the screen is: Total of 2 processors activated (13606.11 BogoMIPS). I diff'd the dmsgs from the before and after the bios upgrade (with acpi=off and debug) diff dmesg /var/log/dmesg 6,7c6,7 < BIOS-e820: 0000000000100000 - 000000007fe5f000 (usable) < BIOS-e820: 000000007fe5f000 - 000000007fee9000 (ACPI NVS) --- > BIOS-e820: 0000000000100000 - 000000007fe5c000 (usable) > BIOS-e820: 000000007fe5c000 - 000000007fee9000 (ACPI NVS) 35c35 < Detected 3401.795 MHz processor. --- > Detected 3400.704 MHz processor. 40c40 < Memory: 2074024k/2096128k available (1961k kernel code, 20452k reserved, 655k data, 200k init, 1178000k highmem) --- > Memory: 2073900k/2096128k available (1961k kernel code, 20452k reserved, 655k data, 200k init, 1177988k highmem) 42c42 < Calibrating delay using timer specific routine.. 6807.51 BogoMIPS (lpj=3403756 ) --- > Calibrating delay using timer specific routine.. 6807.50 BogoMIPS (lpj=3403754 ) 59c59 < Total of 1 processors activated (6807.51 BogoMIPS). --- > Total of 1 processors activated (6807.50 BogoMIPS). 97c97 < MEM window: 95300000-953fffff --- > MEM window: disabled. 101c101 < MEM window: 95400000-954fffff --- > MEM window: disabled. > is after the upgrade. I also diffed the 2.6.16.16 (acpi=off) with knoppix and I've attached that. One question: I built the kernel with hyperthreading enabled. /proc/cpuinfo says it's there, but this is really a dual core chip. Is this a problem? ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------- Using Tomcat but need to do more?
