Hi
I am trying to kexec reboot to a 2.6.15-rc2-mm1 kernel,
with USB builtin, on a x86_64 box, but the system just
hangs during USB initialization.
But strangely, if I comment out the ehci_info() in ehci_run()
in the drivers/usb/host/ehci-hcd.c file, the system successfully
reboots. I fail to understand how ehci_info, which translates to
printk, is a cause of the system hanging.
Any ideas on what could be going wrong would be of great help.
I am attaching the log of the kernel panicing and also the output
of lspci.
Kindly cc me as I am not subscribed to the list.
Thanks
Rachita
