Brief: while booting, system hangs immediately after setting clocksource to tsc, next logged action is ipmi_si reporting no BMC, 500 seconds later.<br />

I have tried adding ipmi_si parameters to the kernel command line in /boot/grub/menu.lst with no effect. <br />
<br />
/proc/cmdline: ro root=UUID=c86ad775-a756-41cb-94ea-726207348bf0 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD rd_NO_DM rhgb noquiet printk.time=1 ipmi_si.type=smic ipmi.type=smic si.type=smic force_kipmid=0<br />
<br />
That's the current version. I have also tried ipmi_si.force_kipmid=0 to turn ipmi off, no effect.
