Hello,
I m facing a problem in RHEL3 (2.4.21-5.ELsmp) kernel while using
kmap_atomic on the pages reserved at the boot time !!!!
At the boot time I reserved pages above 2GB for later use by my module
..... And when I was using those reserved pages through kmap_atomic
system hangs; although kmap_atomic successfully returns me the virtual
address but when I use that virtual address like in memcpy the system
hangs .....
I m unable to findout why it is happening in RHEL3 kernel !!!! Plz
help me in this regard ....
IIRC 2.4.21 has some highmem bugs that have since been fixed. But, it
sounds like you might be doing something quite unusual. Code would
definitely give people a better idea of what might be wrong. You should
definitely consider moving to 2.6 to get a better response.
