| |
I have had problems upgrading dev. kernels since some time after 2.1.89, due to a problem associated with kmod.
Basically, after i boot a new kernel, after a while (to be defined shortly), i start getting kmod: fork errors, and the system becomes unuseable. in the next to latest try (2.1.109), the X display started getting hosed (hard to describe, looks like sync pulses out of whack, causing 'mixing' of scan lines).
In the latest test (2.1.110) the X display didnt get hosed, but the fork errors remained.
Here is what happens:
i boot up, everything is fine, apps work, etc
i start a PPP session (i compiled PPP into kenel rather than module, thinking that would solve kmod errors :-(
things work okay for a while, i download email, etc.
then i start netscape up, it comes up fine, but then i get the fork errors
i modified kmod.c to show which module was called at the time; here is from klog:
... [boot] Jul 22 09:57:41 localhost kernel: Linux version 2.1.110 (root@gustav) ... (gcc version 2.7.2.3.f.1) #1 Tue Jul 21 11:06:50 EDT 1998 Jul 22 09:57:41 localhost kernel: Memory: 63468k/65536k available ... (700k kernel code, 392k reserved, 948k data, 28k init) Jul 22 09:57:41 localhost kernel: Adding Swap: 62492k swap-space ... (priority -1)
[zzzzzzzzzzzzz]
Jul 22 10:04:18 localhost kernel: registered device ppp0 Jul 22 10:05:05 localhost kernel: PPP Deflate Compression module registered
[okay, PPP registered, ppp_deflate.o inserted]
[do some email, etc, no problems]
[start netscape] Jul 22 10:20:51 localhost kernel: kmod: fork failed (module: net-pf-5), errno 11 Jul 22 10:21:32 localhost kernel: kmod: fork failed (module: net-pf-5), errno 11 Jul 22 10:21:32 localhost kernel: kmod: fork failed (module: net-pf-5), errno 11
[followed by lots of fork errors from various processes] [sayonara] ...
now first off, why is net-pf-5 (appletalk) even getting called? second, i have in conf.modules:
## Network stuff alias net-pf-1 unix alias net-pf-2 ipv4 ... alias net-pf-5 off # forget appletalk
yet kmod still gives a fork error.
so my question is, what gives with kmod?????? all other modules seem to work fine. and kerneld has worked flawlessly forever...
all other modules working fine: (gustav)~/: lsmod Module Size Used by ppp_deflate 38952 0 (autoclean) serial 16568 1 (autoclean) aha152x 25072 1 (autoclean) sd_mod 15440 1 (autoclean) scsi_mod 52892 2 (autoclean) [aha152x sd_mod] unix 9548 32 (autoclean) vfat 13572 4 (autoclean) fat 24016 4 (autoclean) [vfat]
