Machine: AMD K6-2 300MHz 64 MB RAM Kernel 2.0.36-0.7 & 2.0.36-3 Sound card Yamaha Opl3Sax kernel hangs when I do : #rec - (rec from the sox package) #cat /dev/audio is OK #cat /dev/dsp is OK #rec /tmp/somefile is OK The message states: Kernel: Free page list corrupt (or some such I am typing offline) The system is then dead, keyboard activity is ok but no disk access at all. A hard reset is needed. Also I can send data to an external MIDI keyboard but I cannot read from it. The commecial OSS drivers both read and write to the external midi port. E. Lefty Kreouzis
The OPL3-SAX driver included in 2.0.36 is the very first version of the driver; it may still have some problems. If you're willing to try one of the 2.2.0pre kernels, that might solve the problem.
I installed 2.2.0-pre5-ac1 and the kernel: VFS corrupt free list disapeared. however I still cannot read midi data from an external keyboard I have. I can play to the external midi keyboard OK. When I tried the commercial OSS drivers I could both write to and read to the external midi keyboard. Maybe I should submit this as a different bug?
I get corrupt freelist problems with zillions of messages on the console and a General Protection Fault in the syslog on one of my key production servers. It crashed twice in the last 24 hours, once so badly I had to run fsck by hand. I'll try to paste in the stuff from /var/log/messages below. System is an Intel 440BX2 motherboard, PII-350MHz, 64MB RAM. While there is a sound card on this system, it is not in use (this is a server, nobody's nearby to listen to music). This hardware replaced a Pentium 133 running RHL 4.2 which ran without flaws for over a year (250 days without a reboot). The kernel is 2.0.36-3. My other servers running 2.0.36-1 have not experienced similar problems, but do not face as much stress. The system that keeps crashing runs qmail and handles large lists. It seems like whenever it has to start paging a lot, it freaks out badly.

The second report from dts@senie.com is unrelated to the first report and probably is an indication of a hardware problem. Alan, do you know about any problems reading from a midi port with the OPL3-SAX driver? Has such a bug been fixed since this was reported? ------- Email Received From Alan Cox <alan@cymru.net> 04/09/99 22:09 -------
