Please disable legacy usb device in bios again. [note: the following instructions presume the use of grub as a bootloader] After you've done this, when you get to the grub kernel selection screen, please move to the kernel you want to be using (2.6.8-5.EL, I would imagine), and type 'a' to add text to the kernel line in question. Enter "reboot=[letter]". Instead of '[letter], however, you will want to use one of 'w', 'c', 'b', or 'h'. 'w' will cause rebooting from the kernel with that added to its commandline to use a 'warm' reboot, which does not test memory or other similar pre-booting type behaviors. 'c' will cause the use of a 'cold' reboot, which will do the memory testing and other pre-booting behaviors which are skipped with a 'warm' reboot. 'b' will cause the use of a 'bios' reboot, which will jump through the BIOS as part of the reboot process. 'h' will cause the use of a 'hard' reboot, by toggling RESET or crashing the CPU (not a terribly nice sounding reboot method, I'd think). One of these should solve your problem. Once you figure out which one does what you want it to, please edit your /etc/grub.conf file and add the appropriate "reboot=[letter]" piece to the kernel line. Thank you for the suggestion. However, I have tried all the above reboot options from grub (before filing this bug), but reboot still fails. Eventhough I am pretty sure I have tested warm, cold, bios, and hard, I will try these one more time to make sure I have not missed anything, and will report the results. Also when I did man bootparam: reboot=[warm|cold][,[bios|hard]]â (Only when CONFIG_BUGi386 is defined.) Since 2.0.22 a reboot is by default a cold reboot. One asks for the old default with âreboot=warmâ. (A cold reboot may be required to reset certain hard- ware, but might destroy not yet written data in a disk cache. A warm reboot may be faster.) By default a reboot is hard, by asking the keyboard controller to pulse the reset line low, but there is at least one type of motherboard where that doesnât work. The option âreboot=biosâ will instead jump through the BIOS. I get the above and I know that CONFIG_BUGi386 is not defined at least not in .config. I am using kernel 2.6.9-5.EL. Does this matter? In other words I am not sure if the above reboot parameters do anything. Thanks. I now have tested all 4 possibilities for kernel reboot parameters, namely, 'b', 'h', 'c', and 'w', and non work. So the current stat is that either I disable the support for legacy usb-devices in bios, resulting in reboot failure, or the touchpad is not recognized and does not work. By the way my cpu is p4-ht, and I have tested both the single processor as well as the smp version of kernel. Thanks. I finally got around building kernel 2.6.10 with psmouse as a module and then loading it in rc.local, with support for legacy usb devices turned on in bios (this used make touchpad not work). The touchpad was recognized and the laptop reboots just fine. It seems that psmouse needs to be loaded after the usb drivers, else the touchpad will not be recognized. Is there anyway to get the sources to the latest kernel in RHEL-4? Thanks. latest sources are at: http://people.redhat.com/~jbaron/rhel4/SRPMS.kernel/ Thank you for submitting this issue for consideration in Red Hat Enterprise Linux. The release for which you requested us to review is now End of Life. Please See https://access.redhat.com/support/policy/updates/errata/ If you would like Red Hat to re-consider your feature request for an active release, please re-open the request via appropriate support channels and provide additional supporting details about the importance of this issue. |
