Description of Problem: This kernel hangs at boot at the message "mxt_scan_bios: enter" unless APM is enabled in the BIOS on an i850 m/b Version-Release number of selected component (if applicable): 2.4.9-34 How Reproducible: Every time Steps to Reproduce: 1. Reboot machine 2. 3. Actual Results: Boot hangs Expected Results: Boot should proceed normally Additional Information:
Did 2.4.9-31 work? What kind of CPU do you have ?
I have seen this with 2.4.9-31, albeit intermittently. A couple of hard reboots seemed to resolve it. CPU is Pentium 4 1700: cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 0 model name : Intel(R) Pentium(R) 4 CPU 1700MHz stepping : 10 cpu MHz : 1694.869 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 3381.65
Hmmm, does booting with mem-nopentium have an effect?
make that mem=nopentium
That doesn't seem to make any difference. In fact, while it happened three times in a row when I reported it, I haven't been able to recreate the boot failure since.
Because of another problem this morning I installed 2.4.19-pre10. It hung in the same place during bootup until I disabled APM support in the kernel configuration.
I'm having a similar problem with 2.4.9-31 on an Intel CA810e MB. It hangs at: mxt_scan_bios: enter But, ONLY if there is no keyboard attached. The BIOS of this machine lacks the ability to disable APM. CPU is PIII-650MHz, Intel i810 chipset. cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Pentium III (Coppermine) stepping : 1 cpu MHz : 648.045 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 1294.33 Any thoughts?
We removed mxt for several reasons, this problem included.
