здравствуйте
опять захотелось новых ядер, поставил 2.6.10-alt3.
почему hotplug pci.rc при загрузке делает так:

ichxrom
(то же самое при ручной загрузке ichxrom. несмотря на can't load module,
загружается и начинает работать автоопределение на pci)
на первой консоли это выглядит так:

хорошо видно, что после глюка все прочие сообщения ядра начинают валиться
прямо в консоль, вместо положенного syslog (в том числе subfs впоследствии, и
т.д.). и при выключении bootsplash на первой портится странным образом.
если в sysconfig/hotplug сделать PCIPLUG=no, то становится легче, но
ненамного: перестает загружаться модуль второй саундухи, несмотря на
alias sound-slot-0 snd-intel8x0
alias sound-slot-1 snd-cmipci
(на рабочем 2.4 это вполне прокатывает).
а почему тогда первая сама загружается? и как теперь реализуется режим
"гвоздями прибил и держится при отключенном хотплаге"? пришлось в rc.local
написать modprobe для обеих звуковых.
еще вот это что:
>home login: warning: process `update' used the obsolete bdflush system call
>Fix your initscripts?
