kernel 2.6.30 upgrade causes dosemu to segfault
I upgraded today to kernel 2.6.30. Dosemu segfaults sometimes immediately, sometimes after a few seconds.
Here is what I got in the syslog:

---[ end trace 536c3bf769ba2533 ]---This is a Gigabyte GA-G31M-S2C motherboard with an integrated NIC RTL 8101E chip (10/100 Mbit). "last sysfs file: /sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/eth0/address" got me thinking that it might be the NIC that is causing all of this. The NIC works very unreliably espaecially under heavy load. It stalls and comes back again or dies altogether requiring a reboot. I see that there are some patches in git concerning the r8169 driver and lots of camplaints about r8169 producing exhibiting similar behavior.
Here is some more info:

Re: kernel 2.6.30 upgrade causes dosemu to segfault
It turns out that my onboard nic problems and dosemu segfaulting are not related. I tried to isolate the cause, so I disbled the onboard nic in bios. Running dosemu still produces the same general protection faults:

---[ end trace b4a58306ed9914f3 ]---Since this thread failed the attention of the devs, I would appreciate at least an answer whether this is an arch specific issue or it has to do with the kernel/dosemu in general. If the latter is the case, then I'll bug the kernel ml.

Re: kernel 2.6.30 upgrade causes dosemu to segfault
n37: I share your experience. I'm compiling kernel26-git atm, I'll report back if it solves the issue. (I tried to run dosemu for my first time with 2.6.30 and it segfaulted from the start) I think its an upstream kernel issue but I'll check first if the newest kernel from git solves the bug before looking deeper into the topic)
Note for interested readers: disable the staging drivers if you have problems to compile the current git kernel.
Best regards, Chris

Re: kernel 2.6.30 upgrade causes dosemu to segfault
n37: It worked! You can compile kernel26-git yourself or I can mail it to you if you want to

Re: kernel 2.6.30 upgrade causes dosemu to segfault
Kernel 2.6.31-git has both of my problems fixed. However, in order to run dosemu I had to set vm.mmap_min_addr = 0.
