It did not hang. When inserting USB disks, I got messages like:
ehci_hcd 0000:00:13.2: Unlink after no-IRQ? Controller is probably using the wrong IRQ. usb 1-1: device not accepting address 2, error -110
and the usb-storage module was not loaded. But the kernel went on working. After upgrading the BIOS, with the same kernel, the USB disk was recognized. But I now notice that the log file, with both old and new BIOS, contains these lines:
ehci_hcd 0000:00:13.2: BIOS handoff failed (160, 01010001) ehci_hcd 0000:00:13.2: continuing after BIOS bug... ehci_hcd 0000:00:13.2: new USB bus registered, assigned bus number 1 ehci_hcd 0000:00:13.2: irq 18, io mem 0xfe02b000 ehci_hcd 0000:00:13.2: USB 2.0 initialized, EHCI 1.00, driver 10 Dec 2004
(only, the IRQ number changed from 10 to 18 after changing BIOS)

I will try that. I saw on apic.c that APIC error 40 should mean 'received illegal vector,' but I have no clue about how to interpret this.
I will now play a bit with BIOS USB parameters.
