What caused the problem for me was the presence of various rd_NO_* kernel parameters in the grub config. In my case it was rd_NO_LVM, but I also saw rd_NO_MD and rd_NO_DM, which may be causing your issue. It seems that the RHEL6 installer puts those kernel parameters in to disable features that it doesn't think you need.<div><br></div><div>Greg<br><div><br><div><div>On May 9, 2013, at 9:12 PM, "Gruher, Joseph R" <<a href="mailto:joseph.r.gruher@intel.com">joseph.r.gruher@intel.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Hello-<o:p></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">I am trying to boot RHEL6.4 over iSCSI using iPXE to start the boot process.

I can actually see RHEL loading for a while so I know boot has begun. However, before boot completes, it crashes as shown in the attached screenshot. My theory is this is happening when the iSCSI connection is handed off from iPXE to the native iSCSI initiator in RHEL, but that is just a guess, I don’t really have any evidence for that being the case. <o:p></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Is this a known problem?
