A couple of days ago I dropped Debian on an Indy I've had lying around for a while. I'd done the first stage of the install, rebooted, and left it sitting at the last half of the Debian installer for a while. When I looked at it an hour or two later, the kernel had spat out the following: Eeek! page_mapcount(page) went negative! (-1) page->flags = 14 page->count = 0 page->mapping = 00000000 Break instruction in kernel code[#1]: Cpu 0 $ 0 : 00000000 1000cc00 ffffffff 8820fe38 $ 4 : 8820fe38 8820fe54 00000001 bf0f0000 $ 8 : 00002085 88260000 0084100b 014f0000 $12 : 89187972 ffffffff 00000029 88260000 $16 : 89125460 1000d000 89125460 10034000 $20 : 89d83d30 88832100 ffffffbf 00000000 $24 : 88260000 88110960 $28 : 89d82000 89d83d08 89333200 8805b06c Hi : 00000000 Lo : 00000027 epc : 880628b8 page_remove_rmap+0xd8/0xe4 Not tainted ra : 8805b06c unmap_vmas+0x508/0x680 Status: 1000cc03 KERNEL EXL IE Cause : 00000024 PrId : 00002020 Modules linked in: unix Process sh (pid: 7040, threadinfo=89d82000, task=8a114ad8) [ etc .. full dmesg output is at http://plaz.net.nz/indy-dmesg.txt ] I think the error may have appeared when the /etc/cron.daily/ scripts started running. I'm running a hand-compiled 2.6.16.11 (I had to drop a new kernel on halfway through the installer because the Debian one has software raid built as modules) Is the message above common? As I said, the Indy has been sitting around doing nothing for quite a while, so the hardware may be a little flaky. I haven't had a chance to test the SIMMs in there, or find others to swap in to test. Thanks, Sam
