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 .... -- Fawad Lateef P.S. My memory reservation and later using that memory through kmap_atomic works well on the kernels other than RHEL3 2.4.21-e.ELsmp .............. the page reservation was done in the arch/i386/mm/init.c file in function one_highpage_init ...... I have Machine with 16GB RAM and 2 - Xeon 2.4GHz Processors ..... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
