[Bug 836220] New: WiFi dies and kernel oopses.
https://bugzilla.novell.com/show_bug.cgi?id=836220 https://bugzilla.novell.com/show_bug.cgi?id=836220#c0 Summary: WiFi dies and kernel oopses. Classification: openSUSE Product: openSUSE 12.3 Version: Final Platform: i586 OS/Version: openSUSE 12.3 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: carlos.e.r@opensuse.org QAContact: qa-bugs@suse.de Found By: --- Blocker: --- Created an attachment (id=553804) --> (http://bugzilla.novell.com/attachment.cgi?id=553804) messages log Pentium IV Laptop, oS 12.3 32 bits. Text mode. System fully patched. While doing largish downloads, the wifi dies and kernel dumps call traces, several times. Attached goes the message log of one session, from boot to halt. When this happens, halt is problematic, but not logged: systemd baulks because /var/lock is busy and will not umount. System does not power off. Halt works if there has been no network crash.

This is a Crap (tainted C) driver earning that distinction. r8712_init_drv_sw calls _r8712_init_sta_priv, which does an order-4 allocation and fails, returning error. r8712_init_drv_sw ignores the error and we crash. This driver is of exceptionally poor quality. Even if we detect the allocation failure and return safely, we'll leak memory. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The laptop is old, has no wifi of its own. This USB-Wifi dongle is thumbnail size, and cheap (about 10€). And boasted "Linux supported" on the box. Too nice to be true... I hopped not to need a cable to connect that lappy.

Carlos, are you comfortable testing these as-is or do you need a kernel built?
Mmmm... I know how to build a kernel (without rpm building), but I'm not sure how to apply the patches. I would need a guide on that part. Besides that, the machine is old, little CPU (P-IV, 32 bits), little RAM (500MiB), little HD (80 GB). At present, the build tools and sources are not installed, but that is a question of time (and hopping they fit into the 12 GiB root partition), then a lonnnng build time as the cpu crawls :-) I would certainly appreciate if you could build the kernel, your facilities are more appropriate than mine this time. If not feasible or inconvenient, I'd need a howto or something to apply the patches. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I see "kernel-syms-3.11.rc7-5.1.g7032523.i586.rpm", I assume the kernel itself will get there later. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I added your test repo in yast, and I installed kernel-default-3.11.rc7-6.1.g7032523.i586.rpm. I rebooted, to runlevel 3. I typed init 5, as usual, but it does not succeed. I only get a mouse in black screen. So I tried to use yast in text mode instead. The network configuration module hangs at "read driver configuration", it stalls. CPU usage is zero. I need to configure network in order to disable eth0 and enable wlan0 instead. I notice that my normal kernel is 3.7.10, whereas yours is 3.11. Are you sure that's ok? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

BTW, I didn't end up seeing this until just now while looking through my bug queue because the NEEDINFO flag was still set. I'll leave it set again for feedback. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From your repo I see 3.11.rc7-6.2g7032526-i586, which is the wrong one. I don't see a kernel-default 3.7.x from your repo, but some kernel-devel packages instead, which I don't suppose are the files you mean.
I'm not sure which kernel I should try this :-? I do not see a kernel 3.7 on your repo. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
