some of my observations:
1. With kernel 2.6.15.4, my system does not get suspended to disk with
the PCMCIA card plugged in. I went through the mailing list

Hi all,
I have a laptop which doesn't have a brandname. It is a 'china make' and
I think is assembled laptop. This laptop uses a promise SATA card, to
which a harddisk is connected. So, during booting it requires a promise
SATA card driver, otherwise Harddisk is not detected properly. I faced
this

I was going through platform_driver structure of "sl811-hcd.c". The

If I do add_timer() multiple times with same timer object as
parameter then the last one will be executed as there can be only one
timer running for a timer object. Now if I call add_timer() multiple

After the bus resume in ohci_bus_resume (), we are doing

ohci_bus_suspend() we are checking some of the conditions.
The below condition is one of the

Hi all,
Can anyone suggest me the significance of HCD_FLAG_SAW_IRQ ?

Please suggest.

Hi,
I am developing a driver for a USB Host Controller (HC) on PCMCIA card.
The Host controller is OHCI based.
I have a doubt. From the specification it seems that once the Host
