Public bug reported:
The system freezes without warning while connected to the internet, usually
within the first 5 minutes of connecting. The caps lock & scroll lock lights
flash repeatedly, the screen freezes and the only way to continue is a hard
reset.
I have reproduced this bug in 2 clean installs of Kubuntu 7.04, and while
running Ubuntu 6.06 from CD (lights do not flash in 6.06).
Steps to reproduce: Connect to a dial-up internet account using either
KPPP or Wvdial (Kubuntu 7.04), or via standard network/ppp configuration
(Ubuntu 6.06). Launch Konqueror or Firefox. Browse one or more
websites for up to 5 minutes.
Actual result: In approximately 95% of attempts, system locks up as
described above. System logs, including kernel logs, show normal
entries for the minutes before the panic, but no errors and no
unexpected entries for the exact time of the panic. In the remaining
~5% of cases, system keeps running as usual.
It first happened within 48 hours of my changing ISP (though not
immediately after changing) so may be ISP-dependant.
Hardware is as follows: Athlon 2200+ with 256MB RAM (32MB used for on-
board Savage4), generic external modem connected to ttys0. Kubuntu
installed on a 10GB primary partition of a 40GB HDD.
The bug appears to be independant of other software running and of the
system's uptime. Both install CDs were checked for errors (none found)
and memtest86+ also reported no errors.
