Без какой-либо видимой закономерности зависают приложения, наблюдается это только в иксах. В dmesg пишется:

Полуркал по форумам - пишут, что это баг в ядре, проявляется на intel'овских видеокартах, с 2.6.27. Каких-то вариантов решения не предлагается. Сталкивался ли кто-нибудь с подобным, может нашли способ забороть?
