2.2.16 SMP: "recvmsg bug: copied 0 seq XXXXXXX"

2.2.16 SMP: "recvmsg bug: copied 0 seq XXXXXXX"

Post by Steve Snyde » Fri, 16 Jun 2000 04:00:00



Ever since I built kernel v2.2.16 with SMP support I have been getting
this message in my system log:

  recvmsg bug: copied 0 seq 93F7B7E

The seq number varies from message to message.

I get this problem when running the DistributedNet RC5 client.  The
problem is seen more frequently when running the client with multiple
threads.  I have been using this same DistributedNet binary since
February (with UP kernels) and have seen no problems until now.

I've searched the mailing list archives and seen several posts
inquiring about this message.  What I haven't seen is a solution to
this situation.

Can someone tell me how to get around this problem?  I'll be happy to
provides any additional info needed.

1. 2.2.16 interesting option "IGNORE word93 Validation BITS"

I wonder what that means ?

Its in the:-

 ATA/IDE/MFM/RLL support  --->
        IDE, ATA and ATAPI Block devices  --->
                IDE chipset support/bugfixes

Hey wait a minute I can't do this, I'm pasting from a GUI
Linux kernel config app (menuconfig) into my newsreader,
and Flatty just told us that Linux doesnt paste with a
mouse!
