Mark, Looking in /usr/src/<linux-version>/arch/s390/kernel/traps.c, routine "do_trap()", you will find the code that generates this message. It looks like the value you are seeing is the Program Interrupt Code (PIC) value from the PSW.
There are some nested (#ifndef/#ifdef/#else) in this area that look like they are related to debugging the kernel during development. In any event, my best guess is that by this point a set of handlers has been installed and when the interrupt is generated, the kernel calls this routine to determine how to handle it, such as calling the Linux version of the Virtual Storage Manager to attempt to determine if an invalid address points to storage that has been paged out, etc. > -----Original Message----- > From: Post, Mark K [mailto:[EMAIL PROTECTED] > Sent: Wednesday, September 29, 2004 06:53 PM > To: [EMAIL PROTECTED] > Subject: Re: Documentation for User Process Faults > > So, when I see a 0x40001 or 0x020001 error, how do I map that to something > in the POP? > > > Mark Post > > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of > Ferguson, Neale > Sent: Wednesday, September 29, 2004 2:48 PM > To: [EMAIL PROTECTED] > Subject: Re: Documentation for User Process Faults > > > The Principles of Operation manual (SA22-7832-03 chapter 6) describes all > the program interruption types. > > -----Original Message----- > > knowing how to interpret the "User process fault: interruption code" > > messages that get generated.
