I understand that the kernel being a critical system element makes a lot of information be needed in order to solve bugs. I'll try to follow the form given for bug reports: 1. Kernel 2.4.21-rcX hangs when trying to access HW clock on a Toshiba DynaBook V4/493PMHW 2. The program hwclock and thus the /etc/init.d scripts hwclock.sh and hwclockfirst.sh are run the computer freezes. No response from the keyboard or mouse. The cursor keeps blinking forever after the Enter key is pressed if 'hwclock --show' is run, for instance, or the computer hangs when it comes to adjust the system clock from the hardware clock while running the /etc/init.d scripts. The HW clock in 2.4.20 works perfectly. 3. Module: Character devices ---> Enhanced Real Time Clock Support 4. Linux version 2.4.21-rc7-ac1 (root@roamer) (gcc version 2.95.4 20011002 (Debian prerelease)) -- Also happened in rc2 and rc5. 5. No Oops... 6. hwclock --show or /etc/init.d/hwclock.sh 7.1. ver_linux : If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.
