| |
i tried to use the sppedstep-ich module on my P4M-HT (stepping 9 533 MHz FSB). the cpuinfo_x86 reports an ebx=0x08. after adding this to the allowed cases in speedstep_detect_processor in speedstep-lib.c, the module loads fine and does voltage scaling correctly. however, after a random amont of time, the system freezes solid. if i enable the debug option, the last syslog entries are:
Jun 1 23:20:18 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0x17310b17 0x0 Jun 1 23:20:18 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 23 Jun 1 23:20:18 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0xc310b17 0x0 Jun 1 23:20:18 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 12 Jun 1 23:20:38 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0xc310b17 0x0 Jun 1 23:20:38 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 12 Jun 1 23:20:38 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0x17310b17 0x0 Jun 1 23:20:38 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 23 Jun 1 23:20:48 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0x17310b17 0x0 Jun 1 23:20:48 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 23 Jun 1 23:20:48 cookie speedstep-lib: P4 - MSR_EBC_FREQUENCY_ID: 0xc310b17 0x0 Jun 1 23:20:48 cookie speedstep-lib: P4 - FSB 133330 kHz; Multiplier 12 followed by hundreds of NULL-characters.
i tested it on kernels 2.6.5, 2.6.6 and 2.6.7-rc1 with SMP and preempt.
i am trying to fix this problem, but i am very inexperienced in kernel programming and would appreciate any hint/help.
