One place where the system crashes is at dmi scan time, because __ioremap() is a "return NULL" when CONFIG_XEN_PHYSDEV_ACCESS is not defined, which makes dmi_iterate's memcpy follow a NULL pointer.Which kernel is your patch against? The plain 2.6.10 dmi_scan.c only uses bt_ioremap() AFAICT, and it already checks the return value for NULL. This is 2.6.11-rc1. -- "Debugging is twice as hard as writing the code in the first place.
