Can't apply IPS-K9-patch-5.1-1p1

[6aganguly]

Upgraded my 5.0-1c IDSM2 blade to 5.1-1f and then to 5.1-3 but had not applied the 5.1-1p1 patch before this last upgrade. Monitoring ports kept becoming error-disabled. Downgraded to 5.1-1f in order to apply the patch but now keep getting:

Error: execUpgradeSoftware : This update requires that version IPS-K9-min-5.1-1 be installed prior to update.

even though a "sh ver" tells me I am at 5.1(1)

Has anybody come across this before?

You do not have to apply the p1 patch. It is rolled up into 5.1(2) and now 5.1(3). If your ports are becoming err-disabled, its for something not associated with the p1 patch. The usual cause is trying to hard-code the port speed or duplex.
