2.1.90-2 oops: tcp_v4_hash: PageFault

Hello,
it looks like that it is time to update to 2.1.90-3 because of
today, at 15:08 MET, my machine died after ~3 days uptime. When I come
in, at 15:30, machine was completely dead (no IP, no SCSI activity
(AIC7870), no keyboard LEDs...). It was first oops in 2.1.x for me
(I'm using them since 2.1.75), so I do not think that it is easy
reproducible on my machine.
FYI, toCP1250 is perl cgi-script which forwards HTTP request to local WWW
server, and then converts server's reply from ISO-8859-2 to CP1250 charset
if that reply was of type text/*.
FYI2, machine is UP, but kernel is SMP.
