OK we've verified on 2 separate systems with Athlon XP that reverting the commit fixes the issue. Here's proc/cpuinfo and relevant dmesg output for reference: processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 10 model name : AMD Athlon(tm) XP 2600+ stepping : 0 cpu MHz : 1920.500 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow up bogomips : 3842.29 clflush size : 32 power management: ts [ 0.461404] Freeing initrd memory: 5191k freed [ 0.467844] initcall populate_rootfs+0x0/0x62 returned 0 after 217975 usecs [ 0.467947] calling i8259A_init_sysfs+0x0/0x1d @ 1 [ 0.468093] initcall i8259A_init_sysfs+0x0/0x1d returned 0 after 41 usecs [ 0.468190] calling sbf_init+0x0/0xda @ 1 [ 0.468282] initcall sbf_init+0x0/0xda returned 0 after 0 usecs [ 0.468378] calling i8237A_init_sysfs+0x0/0x1d @ 1 [ 0.468484] initcall i8237A_init_sysfs+0x0/0x1d returned 0 after 12 usecs [ 0.468582] calling add_rtc_cmos+0x0/0x94 @ 1 [ 0.468679] initcall add_rtc_cmos+0x0/0x94 returned 0 after 4 usecs [ 0.468780] calling cache_sysfs_init+0x0/0x55 @ 1 [ 0.468940] initcall cache_sysfs_init+0x0/0x55 returned 0 after 64 usecs [ 0.469041] calling cpu_debug_init+0x0/0x1f @ 1 [ 0.469190] cpu0(1) debug files 5 [ 0.469282] initcall cpu_debug_init+0x0/0x1f returned 0 after 143 usecs <-- That call wasn't returning at all I think that the commit should be reverted or a fix should be released for linux-2.6 tree, as well as .31 and .32 stable trees.
