I see this as well, on booting a Dell OpiPlex XL 590, and can also reproduce it by restarting microcode_ctl: [root@louisa root]# /etc/init.d/microcode_ctl restart Applying Intel IA32 Microcode update: [ OK ] [root@louisa root]# Jan 12 01:15:50 louisa modprobe: modprobe: Can't locate module char-major-10-184 Jan 12 01:15:50 louisa microcode_ctl: microcode_ctl startup succeeded [root@louisa root]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 5 model : 2 model name : Pentium 75 - 200 stepping : 5 cpu MHz : 90.029 fdiv_bug : no hlt_bug : no f00f_bug : yes coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr mce cx8 bogomips : 179.40 Also on Pentium 4.(Dell precision) Red Hat 7.2 [root@ip68-9-128-179 log]# date Mon Jan 19 13:25:47 EST 2004 [root@ip68-9-128-179 log]# /etc/init.d/microcode_ctl restart Applying Intel IA32 Microcode update: [ OK ] [root@ip68-9-128-179 log]# tail -2 /var/log/messages Jan 19 13:25:57 ip68-9-128-179 modprobe: modprobe: Can't locate module char-major-10-184 Jan 19 13:25:57 ip68-9-128-179 microcode_ctl: microcode_ctl startup succeeded [root@ip68-9-128-179 log]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 1 model name : Intel(R) Pentium(R) 4 CPU 1.70GHz stepping : 2 cpu MHz : 1694.889 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 I get this modprobe error sometimes too on my i586, however it at least seems to be intermittent and rare in occurence for me, IA32 Microcode Update normally at least indicates it loads [OK] on boot. [gulo@joker gulo]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 5 model : 4 model name : Pentium MMX stepping : 3 cpu MHz : 232.275 fdiv_bug : no hlt_bug : no f00f_bug : yes coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr mce cx8 mmx bogomips : 463.66 RE above comment, modprobe error is no longer intermittent on that machine, says it can't locate the module char-major-10-184 every boot now, this change possibly happened after an up2date. 586 CPU's don't have the microcode feature at all, so microcode_ctl shouldn't be doing anything at all in this situation. I get his on my toshiba P1 266 notebook at every boot. I'm guessing this is a module dependency or aliasing problem, nothing to do with microcode. Paul a solution to this problem is to do: chmod 644 /dev/cpu/0/microcode still a problem in fc3 ? for rawhide, I've added a check for < 686's that makes microcode_ctl exit immediately. Seems to work for me in FC3 |
