FW Q.11.26 crashes 2510-24 switch

Hi all.
I just got a 2510-24 switch which came loaded with Q.11.17 software. I wanted to update to Q.11.26, which is the latest, but when I do, the switch becomes unresponsive on telnet and web agent interfaces.
The switch does forward packets, I just can't configure it anymore. It makes no difference if I load Q.11.26 in the primary or secondary or if I am running in the primary or secondary. Pings are slow too (approx. 14ms) on a direct connection.
The only way out is to restore Q11.17 in both images and factory reset the switch.

Very nasty.

Any ideas what is going on?

Best regards
Jens

Having restored, ping are bad in general: between 1 and 10 ms response, very often 1-2 timeouts per 4 pings.

Could I have a bad switch on my hands or are all 2510-24s like this?

After moving the switch onto a quiet branch on the network and then upgrading both firmware images from Q.11.17 to Q.11.26 (secondary first), the problem went away.

I don't know what caused the problem as I have frequently updated firmware on much heavier loaded switches.

Oh well ...
