Subject: 2.6.23-rc2: WARNING: at kernel/irq/resend.c:70 check_irq_resend()


Hi,

I'm opening this ticket as a new subject, even though it looks like it
might be related to the thread "Networking dies after random time".
Sorry for the wide CC list, but since my network hasn't died since I
rebooted into 2.6.23-rc2 (after 30+ days at 2.6.22-rc7), I'm wondering
if the problem is more than networking related.  

Honestly, I haven't gone back over the previous thread in detail, so I
might be missing info here.

System details: Dell Precision 610MT, Intel 440GX chipset, Dual PIII
Xeon, 550Mhz, 2gb RAM (upgraded from 768Mb last night), a mix of IDE,
SCSI and SATA disks in the system.  My poor PCI bus!  Just upgraded to
2.6.23-rc2.  Interrupts looks like this:

I've only seen the one Warning oops, and backups and other system
processes have been running for the past 12 hours without a problem.
