NULL pointer In-Reply-To: [EMAIL PROTECTED] References: [EMAIL PROTECTED] X-Mailer: VM 6.75 under 21.1 (patch 14) Cuyahoga Valley XEmacs Lucid Seems that Aaron's problem is more substantial than just cardmgr. I also started to get kernel Oops of the kind (pcmcia unrelated): Unable to handle paging request Unable to handle kernel NULL pointer dereference in Mandrake Linux Release 8.2 (Bluebird) kernel 2.4.18-6mdk It looks like the virtual memory management system is buggy (just a guess). Question: is it Mandrake's or www.kernel.org problem and who could be interested in getting/fixing such bug reports? Aaron Peromsik writes: Hi, Last weekend I installed the 8.2 download edition. In general I am impressed. However, I can't install on my wife's machine until the following shutdown issue is addressed: I get a kernel panic when cardmgr tries to shut down. My machine is a Sony Vaio F-340, and the card in question is a BusLink wireless network card (uses the ray_cs driver). The desktop machine which I haven't tried yet has a similar card, WebGear Aviator PRO. Both cards and both machines work fine with Mandrake 8.1, except that (for both 8.1 and 8.2) I had to manually change the essid in /etc/pcmcia/config.opts despite setting it during installation. My kernel panic looks like this: - [root@grover root]# service pcmcia stop Shutting down PCMCIA services: cardmgrUnable to handle kernel paging request at virtual address ccc6a0001 *pde = 0b0d4067 *pte = Oops: CPU: 0 EIP: 0010:[ccc66fd5] Not tainted EFLAGS: 00010246 eax: ebx: caad3440 ecx: cb6bda00 edx: ccc6a000 esi: cb0fa800 edi: 0003 ebp: cb7b1c04 esp: cb6b1bb4 ds: 0018 es: 0018 ss: 0018 Process cardmgr (pid: 819, stackpage=cb7b1000) Stack: caad3440 0001 0003 c010836a 0003 cb6bda00 cb7b1c04 cb7b1c04 0003 c02bb960 caad3440 c01084ed 0003 cb7b1c04 caad3440 ccc5e000 0580 cabdf00c ccc5a0c8 c022af98 ccc5e000 0200 05d0 0580 Call Trace: [c010836a] [c01084ed] [ccc5a0c8] [ccc5a0c8] [ccc50018] [ccc5892c] [ccc5821d] [ccc5a0c8] [ccc500a3] [ccc51c29] [ccc65c3a] [ccc68d20] [ccc65308] [ccc60875] [ccc611aa] [ccbb8481] [ccbabd19] [ccbada5f] [c01c4f67] [c0176b4a] [c0125334] [c01258ca] [c0114de8] [c0125d0d] [c01260b4] [c0141617] [c0106f23] Code: 8a 42 01 84 c0 79 0c 89 74 24 10 5b 5e 5f e9 e8 0b 00 00 3c 0Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing - I get the same thing when doing just cardctl eject. But if I take the card out manually, the drivers clean themselves up just fine. If there's anything I can do to help track this down please let me know. I'd like to see this addressed in updates or at least have a way to hack the scripts to work around it so that my wife can start using some of the new features of 8.2 on her machine.

[expert] kernel: Unable to handle kernel paging request at virtual address 46390000
Hi! My ML 8.2 with (no kernel changes) Linux version 2.4.18-6mdk ([EMAIL PROTECTED]) (gcc version 2.96 2731 (Mandrake Linux 8.2 2.96-0.76mdk)) #1 Fri Mar 15 02:59:08 CET 2002 running on MSI K7T266 Pro with AMD Athlon 1.4GHz and 768MB of DDR266 breaks with the following kernel Oops when running a big and greedy Sun java 1.4 program taking almost all memory. Any ideas/suggestions? Is it kernel/motherboard/memory/java?

[expert] kernel, bad swap file entry, and X
Hi! Periodically my X server (from ML8.2, on NVidia Geforce MX400 graphic card) dies unexpectedly, with the following message to /var/log/messages. Any remedies known? Should I blame the kernel or the X server, or myself? Earlier today I reported a problem with the kernel: Unable to handle kernel paging request at virtual address (surely, I rebooted the system) Thanks, Sergei --- from /var/log/messages Apr 12 11:41:20 nash kernel: swap_dup: Bad swap file entry 0041c720 Apr 12 11:41:20 nash kernel: VM: killing process X Apr 12 11:41:20 nash kernel: swap_free: Bad swap file entry 0041c720 Apr 12 11:41:22 nash kdm[2328]: Server for display :0 terminated unexpectedly Apr 12 11:41:25 nash kde(pam_unix)[2345]: session closed for user sergei Apr 12 11:41:25 nash su(pam_unix)[3539]: session closed for user sven Apr 12 11:41:25 nash su(pam_unix)[3095]: session closed for user root Apr 12 11:41:30 nash kdm[3678]: session start failed -- Sergei Vorobyov Information Technology/ Computing Science Department Uppsala University Box 337 S-751 05 Uppsala Sweden Want to buy your Pack or Services from MandrakeSoft?
