(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! I cannot provide any info as I do not have an access to this hardware. I had at the time I filed the bug but this was over a year ago and nobody looked particularly interested. |
Description of problem: On P5B Asus board with Intel(R) Core(TM)2 CPU and 4 GB of installed memory an attempt to boot 2.6.18-1.2798.fc6 or 2.6.18-1.2868.fc6 causes an instant lockup pretty close to a beginnig of the whole boot sequence _provided_ "memory reallocation" feature in BIOS is _not_ disabled. OTOH if you will do this disabling then a machine does boot but it is loosing a gig of memory with an output of 'free -m' as follows: total used free shared buffers cached Mem: 2948 559 2389 0 17 335 -/+ buffers/cache: 205 2742 Swap: 1983 0 1983 Updating to the latest available BIOS does not help. A lockup happens pretty much at the beginning of the whole boot. At least whatever is printed on a screen scrolls way too fast for anybody to read anything out of that and after that there is no reaction to anything whatsoever (and there is no serial port so no way to try to capture an output that way). I attach two screen pictures with whatever is frozen on screen. One from 2.6.18-1.2798.fc6 boot and one from 2.6.18-1.2868.fc6. They do not differ that much with an exception of "CR2" on the screen top, which is not even in the same range, and slightly different address for _sinittext. Apart of these two picturea attached are a dmesg output from a boot with a "memory reallocation" disabled, and from 'cat /proc/cpuinfo', from 'dmidecode' and from 'lspci -tv'. How reproducible: As described - always, unfortunately.
