Pressing the reset button does have the effect of resetting the machine, but the boot still hangs after grub unless the power is cycled. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Adding debug initcall_debug to kernel command line gets as far as early console in setup code.

What does this mean? Could you take a photo? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However we need PXE boot for provisioning machines. Given that the kernel boots as far as somewhere in arch/x86/boot/main.c (at least), this would still seem to be a kernel bug. Is there any other debugging I can do, now that I can reliably reproduce this? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Created an attachment (id=425283) --> (http://bugzilla.novell.com/attachment.cgi?id=425283) [details] [details] photo with initcall_debug

This photo (with "debug initcall_debug") shows that the kernel gets to "early console in setup code".

Aha, got it. Sorry it took me so long. So now, I'm curious whether we get as far as EDD or video setup. Remove quiet option and use something like vga=0xabc. So the command-line would look like: root=/... debug initcall_debug vga=0xabc

No, it stops at the same place. Tried adding edd=off and it doesn't even get as far as that (i.e. it doesn't print "early console in setup code"). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
