Spurious interrupts on a 2821
Hi,
For the 3rd time in a month I had a lot of 'spurious interrupts' on a 2821 with a HWIC-1ADSL running on IOS 12.4(11)T Advanced Enterprise Services:
Jan 25 10:01:08: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF.

After this the router is completely unreachable. When I reset the router everything is OK again for a week or so. The only information I can find on the cisco website about this errormessages is that this are debug-messages only, and that no action is required:
Thanks in advance! Roel Koops
