hang in ioremap called from detect() entry point of scsi hba driv

[MEHTA,HIREN]

Hi List,

I am trying to call ioremap() from the detect() routine  of the
scsi hba driver to map the memory mapped and i/o mapped registers 
on the card. I have two HBAs supported by the driver. For the first 
card, everything works fine (including ioremap). Whereas for the second 
card, the ioremap for the memory mapped register is hanging. I am 
running 2.4.2 kernel on i386 and new error handling code is enabled 
in the scsi hba driver (use_new_eh_code = 1). Any idea what might 
be wrong ? This is working fine under 2.2.x kernel. If you need
more information, please let me know.

TIA.
Regards,
