I thought we'd fixed this hang?  It's been known about for a
month or so?

Subject: [Bugme-new] [Bug 6098] New: EHCI handoff causes boot hang


http://bugzilla.kernel.org/show_bug.cgi?id=6098

           Summary: EHCI handoff causes boot hang
    Kernel Version: 2.6.16-rc4
            Status: NEW
          Severity: normal
             Owner: [EMAIL PROTECTED]
         Submitter: [EMAIL PROTECTED]
                CC: [EMAIL PROTECTED],[EMAIL PROTECTED]


This is a regression that started in 2.6.15 - 2.6.14 booted OK at all times
(handoff option has not been tried).

2.6.15 and newer hangs on warm boot at this line:
io scheduler cfq registered

Cold boot works fine, and this problem doesn't happen on *every* warm boot (but
does occur most of the time).

Further investigation shows that it hangs in quirk_usb_disable_ehci() at this 
point:

                        /* always say Linux will own the hardware
                         * by setting EHCI_USBLEGSUP_OS.
                         */
                        pci_write_config_byte(pdev, offset + 3, 1);

The pci_write_config_byte call never returns. This happens on the first
iteration of the loop.

This is an ICH-based system with a Pentium 4 CPU.

I'm reporting this on behalf of Tersius.
