Hi, Commit e9e2cdb412412326c4827fc78ba27f410d837e6e breaks boot on a Dell E1501 unless 'acpi=off' is specified (also tried nolapic and nohpet but it made no substantive difference). This laptop is an 'AMD Turion(tm) 64 X2 Mobile Technology TL-50' CPU, but its booting 32 bit SMP (make defconfig). No kernel built after this commit works for this platform. There is no crash output, it just wedges after 'NET: Registered protocol family 2'. How can I debug this problem? rtg -- Tim Gardner tim.gardner@xxxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
