Rawhide just came out with 3.1.0-0.rc6.git0.0.fc17.x86_64 , and the BUG:s are
still the same as in the last log I sent. However, as promised I have attached
the initcall_debug log, but for rc6.
I had an interesting problem with my grub stanza that made me fear that it was
back to not booting at all under xen. It looked just like the same problem
that rc0 and rc1 had. The problem was that the xen option
'serial_tx_buffer=64k' was too small, and was causing the boot to stall. I
upped the buffer to 256k. I'm including the output from the too small buffer
below, merely for amusement - it was my problem, not xen's.
Using the following grub stanza:
title Xen Dom0 w/debug console (3.1.0-0.rcx.gity.z.fc17.x86_64)
root (hd0,1)
kernel /xen.gz cpufreq=xen loglvl=all guest_loglvl=all
serial_tx_buffer=256k console_to_ring noreboot com1=115200,8n1,0xdff8,19
console=com1
module /vmlinuz ro root=/dev/mapper/vg_insp6400-lv_root
SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=us console=hvc0
earlyprintk=xen nomodeset initcall_debug debug loglevel=10
module /initramfs
where vmlinuz and initramfs are soft links, and x,y,z is rc5.git0.0 for the
attached file with 'initcall_debug', and rc6.git0.0 for the (unimportant)
crash shown below (with the 64k buffer).

That has been correct for rc2 - rc6. From an earlier post in the original
