padajacy kernel 2.4

[Jarek Woloszyn]

Ostatnio zmienilem kernel na 2.4.2 i zaczely sie pojawiac niespodzianki:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
 printing eip:
c01420e6
*pde = 00000000
Oops: 0000

Ciekawe jest to:
Process rpm (pid: 2405, stackpage=c262d000)
Process rpm (pid: 2463, stackpage=c0ec5000)
Process alsactl (pid: 12689, stackpage=c18d7000)

Process chmod (pid: 2450, stackpage=c137b000)
Process chown (pid: 2379, stackpage=c14b7000)
Process chmod (pid: 2384, stackpage=c23ed000)
Process chmod (pid: 2386, stackpage=c23ed000)
Process slocate (pid: 2320, stackpage=c2dbb000)
Process chmod (pid: 8001, stackpage=c1925000)

Komunikat zawsze ten sam:
Unable to handle kernel NULL pointer dereference at virtual address ****** 

Z 2.2 nie bylo takich problemow.
Zrobilem upgrade wszystkiego co bylo opisane w Changes kernela.

Wywalil sie tak 11 razy w ciagu 4 dni.
