Assaf -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Greg Ungerer Sent: Friday, March 30, 2007 10:00 To: uClinux development list Subject: Re: [uClinux-dev] BUG: scheduling while atomic Hi Arnon, Assaf, I see one problem in the modules/ixp425/net-2.1/ixp400_eth.c code. It is using the define CONFIG_ARCH_IXDPG425 for conditionals, it should be CONFIG_MACH_IXDPG425. At least everything seems to work fine with no preemption after that is fixed. Now with preempt enabled I get all sorts of oops if I have the IXP425 ETHDB option enabled. But it seems to run clean if I disable that. (You can disable it in the modules options config, in the ixp400 driver section). Is that consistent with what you see? So it sure looks like a problem in the EthDB handling code.
